Bug Report
If the "dummy" variable _ is used several times in assignments as shown in the following code snippet, we get an error, because different expressions return different types.
IMHO, this _ variable shouldn't be checked for typing in assignments, because it is freely used to throw away all types of returned results.

To Reproduce

def f1() -> int:
    return 5

def f2() -> str:
    return "5"

_ = f1()
_ = f2()

Expected Behavior
No error message.

Actual Behavior

mypy-test.py:8: error: Incompatible types in assignment (expression has type "str", variable has type "int")  [assignment]
Found 1 error in 1 file (checked 1 source file)
