Merge https://github.com/mypyc/mypyc into merge-mypyc
The mypyc history was rewritten before this merge to fix up PR and issue references to be cross-repo references. The command was `git filter-branch -f --msg-filter 'sed "s@\(^\|[ (]\)\(#[0-9]\+\)@\1mypyc/mypyc\2@g"'`

mypyc: Mypy to Python C Extension Compiler
2+
==========================================
3+
4+
*Mypyc is (mostly) not yet useful for general Python development.*
5+
6+
Mypyc is a compiler that compiles mypy-annotated, statically typed
7+
Python modules into CPython C extensions. Currently our primary focus
8+
is on making mypy faster through compilation -- the default mypy wheels
9+
are compiled with mypyc. Compiled mypy is about 4x faster than
10+
without compilation.
11+
12+
Mypyc compiles what is essentially a Python language variant using "strict"
13+
semantics. This means (among some other things):
14+
15+
* Most type annotations are enforced at runtime (raising ``TypeError`` on mismatch)
16+
17+
* Classes are compiled into extension classes without ``__dict__``
18+
(much, but not quite, like if they used ``__slots__``)
19+
20+
* Monkey patching doesn't work
21+
22+
* Instance attributes won't fall back to class attributes if undefined
23+
24+
* Metaclasses not supported
25+
26+
* Also there are still a bunch of bad bugs and unsupported features :)
27+
28+
Compiled modules can import arbitrary Python modules, and compiled modules
29+
can be used from other Python modules. Typically mypyc is used to only
30+
compile modules that contain performance bottlenecks.
31+
32+
You can run compiled modules also as normal, interpreted Python
33+
modules, since mypyc targets valid Python code. This means that
34+
all Python developer tools and debuggers can be used.
35+
36+
macOS Requirements
37+
------------------
38+
39+
* macOS Sierra or later
40+
41+
* Xcode command line tools
42+
43+
* Python 3.5+ from python.org (other versions are untested)
44+
45+
Linux Requirements
46+
------------------
47+
48+
* A recent enough C/C++ build environment
49+
50+
* Python 3.5+
51+
52+
Windows Requirements
53+
--------------------
54+
55+
* Windows has been tested with Windows 10 and MSVC 2017.
56+
57+
* Python 3.5+
58+
59+
Quick Start for Contributors
60+
----------------------------
61+
62+
First clone the mypy git repository *and git submodules*:
63+
64+
$ git clone --recurse-submodules https://github.com/mypyc/mypy.git
65+
$ cd mypy
66+
67+
Optionally create a virtualenv (recommended):
68+
69+
$ virtualenv -p python3 <directory>
70+
$ source <directory>/bin/activate
71+
72+
Then install the dependencies:
73+
74+
$ python3 -m pip install -r test-requirements.txt
75+
76+
Now you can run the tests:
77+
78+
$ pytest mypyc
79+
80+
Look at the [issue tracker](https://github.com/mypyc/mypyc/issues)
81+
for things to work on. Please express your interest in working on an
82+
issue by adding a comment before doing any significant work, since
83+
development is currently very active and there is real risk of duplicate
84+
work.
85+
86+
Note that the issue tracker is still hosted on the mypyc project, not
87+
with mypy itself.
88+
89+
Documentation
90+
-------------
91+
92+
We have some [developer documentation](doc/dev-intro.md).
93+
94+
Development Status and Roadmap
95+
------------------------------
96+
97+
These are the current planned major milestones:
98+
99+
1. [DONE] Support a smallish but useful Python subset. Focus on compiling
100+
single modules, while the rest of the program is interpreted and does not
101+
need to be type checked.
102+
103+
2. [DONE] Support compiling multiple modules as a single compilation unit (or
104+
dynamic linking of compiled modules). Without this inter-module
105+
calls will use slower Python-level objects, wrapper functions and
106+
Python namespaces.
107+
108+
3. [DONE] Mypyc can compile mypy.
109+
110+
4. [DONE] Optimize some important performance bottlenecks.
111+
112+
5. [PARTIALLY DONE] Generate useful errors for code that uses unsupported Python
113+
features instead of crashing or generating bad code.
114+
115+
6. [DONE] Release a version of mypy that includes a compiled mypy.
116+
117+
7a. More feature/compatibility work. (100% compatibility with Python is distinctly
118+
an anti-goal, but more than we have now is a good idea.)
119+
120+
7b. Support compiling Black, which is a prominent tool that could benefit
121+
and has maintainer buy-in.
122+
(Let us know if you maintain another Python tool or library and are
123+
interested in working with us on this!)
124+
125+
7c. More optimization! Code size reductions in particular are likely to
126+
be valuable and will speed up mypyc compilation.
127+
128+
8. We'll see! Adventure is out there!
129+
130+
Future
131+
------
132+
133+
We have some ideas for
134+
[future improvements and optimizations](doc/future.md).
