digitalmars.D.learn - Why non- property functions don't need parentheses

Hi,

I was wondering, why are we allowed to omit parentheses when calling functions
with no arguments, when they are not  properties? Is there a good reason for
relaxing the language rules like this?

Thanks!

This behavior is deprecated, but other features have had a higher priority
than removing features that do not cause big trouble. :p

Because the compiler is not in line with TDPL yet. It used to be that  property 
didn't even exist and _all_ functions which returned a value and took no 
parameters could be used as a getter property and _all_ functions which
returned 
void and took a single value could be used as a setter property.  property was 
added so that it could be better controlled. However, while  property has been 
added, the compiler has yet to be changed to enforce that  property functions 
are called without parens and that non- property functions are called with
them. 
It will be fixed at some point, but it hasn't been yet.
