Detailed Description

This file provides a collection of function (or more generally, callable) type erasure utilities supplementing those provided by the standard library in <function>.

It provides unique_function, which works like std::function but supports move-only callable objects.

Future plans:

Note that LLVM's utilities are greatly simplified by not supporting allocators.

If the standard library ever begins to provide comparable facilities we can consider switching to those.
