One of the differences between D and C seems
to be that I am able to call D functions without
parameters by simply omitting the empty
brackets:
So
test();
or
test;
will give equivalent results.
In C only the first statement will work. The
other one will result in a warning and otherwise
gets ignored.
I am lazy enough to like the idea that I can
omit the brackets if I'd wish to, but I also
want to ensure that future versions of dmd
will still allow me to do that.

Firstly, it _looks_ like an effectless (and therefore illegal) statement, and as such is likely to arouse the suspicion of anybody who reads the code. Secondly, I had previously got the impression that, when you use a function name, you had to do one of the following with it: - assign to it - use it as an rvalue in an expression - take its address Using it on its own for an ExpressionStatement isn't doing any of these, and so there's nothing disambiguating how the function name is being used.
