Syntax don't have to be changed, unless templates are not allowed
(syntactically) in interfaces (I'm too lazy to check right now :).

And template syntax don't have to change either. This is already valid
AFAIK syntax AFAIK. What it has to be changed, is the semantics, because
int opGet(foo)(); should be interpreted as a read property instead of
a templated function.

Yes, and...?
