I've always secretly hated the ambiguity in D's syntax. E.g:
foo.bar
What could foo and bar be? D has many more answers than C++:
D C++
foo bar foo bar
Module/Namespace x x
Type x x
Variable x x x x
Method x
Free function x x
For this reason I initially agreed with Nick Sabalausky on
disallowing calling non-property functions without parenthesis.
...but now I'm thinking that this ambiguity stops being an issue
once we have an IDE that can render different things in different
colors (or different fonts or with other visual cues if you're
color-blind). Color is a much stronger and faster visual cue than
having parenthesis at the end of a name. For this reason, I think
that it's fine to allow non-property functions to be called
without parenthesis. But I still think that property functions
should not be allowed to be called with parenthesis.
