You could do that, but why?  The annotations are there to allow the compiler
to make your life easier, not dramatically harder.  It's hard enough to add
the annotations in the first place -- don't make it any harder.

Also, the type annotations are intrinsically a part of the function they're
annotating.  They have absolutely ZERO use outside of that function.
