A function literal should be comparable to another for

Are you willing to explain me why, and show an use case?
An important application is optimizing for specific lambdas (e.g.
equality). For example, a substring search using equality for
characters could use bitwise comparison.
Is there some reason this isn't better handled through templating
mechanisms? It seems like this would primarily benefit picking
better optimization strategies at *runtime*, which strikes me as a
fairly esoteric use case.

Forgot to mention - the comparison should work statically, i.e. inside a
static if.
