D's lexical structure, though. The lexer will have to
understand it as
(int:5)(.)(ident:hours) rather than (float:5.)(ident:hours).
And then if
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.
