Thx.

Use @property when you want a pseudo-variable or something that
might be conceptually considered a "property" of the object,
i.e. to do this:
auto blah = thing.someProperty;
thing.someProperty = blahblah;
or
struct myArray(T)
{
T[] arr;
@property size_t memSize() { return arr.length * T.sizeof; }
}
Other than that, don't use it. Ordinary functions can be called
without parenthesis anyway.
Using those ideas you shouldn't run in to any surprises.
Oh, but don't expect the compiler to enforce this and please
don't use the -property flag, it will only cause you pain.
