Supporting stuff like 5.hours will introduce additional complications to
D's lexical structure, though. The lexer will have to understand it as

you actually *wanted* a float, you'd have another ambiguity: 5..hours
could mean (float:5.)(.)(ident:hours) or (int:5)(..)(hours). And
5.0.hours just looks... weird.

Actually, Kenji's pull request for UFCS already takes care of this.
Things like 5. aren't allowed, nor is 5.f; a number has to follow the
decimal. So 5.f would invoke UFCS function f with the integer 5. I
believe this change is already merged, though the rest of the UFCS pull
request isn't unfortunately.
I can definitely confirm that porting C/C++ floating point literals to D
is a huge pain in the ass because of this change, so its definitely in
to the degree it breaks my math and physics libs heavily :)
