Looks nice. Though, I see it has some problems that stuck me 
before. The traits isFunctionOver and isUnaryOver can't handle 
lambdas that receive arguments by ref like:

struct S {}
static assert(isFunctionOver!((ref s) => s, S));

I wish ref was part of the type in D, so we could pass ref S as 
template parameters. I could pass as string but it's error prone 
and not really elegant.
