Some array libraries implement a .copy() method (like NumPy). While there are some indirect ways to get at this now (asarray, reshape, etc.), currently the API lacks a way to do this directly and without other potential side-effects. Should add a method (unlike a function) would ensure the new array has the original array's type simply. Curious if there is appetite for including this in the API.

Related is a question of what interplay there is with __copy__ and/or __deepcopy__ (if any).
