You're probably thinking of the special optional/non-optional
parenthesis rules and the -property compiler switch which was removed.
@property should still be used according to the style guide:
https://dlang.org/dstyle.html
and as far as I can tell it's heavily used in phobos.
Properties behave more like field variables in some traits:
http://dlang.org/spec/traits.html
https://dlang.org/phobos/std_traits.html
But I think that's the only relevant difference between properties and
normal functions right now.
