Just style. For me is ugly to see a procedure call like Foo().

C resolves the problem by > the 'void' type, I don't like that approach. Oberon uses 'procedure' too. Maybe: a) New sintaxe for "procedure": function func(a: bool8); begin // do not need the return keyword end; b) New sintaxe for "function": function func(a: bool8): int32; begin // do need the return keyword return 123; end; -- Marcos Douglas PS: Do you will continue using "begin" for procedures/functions/methods? Maybe you need to cut in these cases too. ;-) Eg: function func(a: bool8): int32; return 123; end; ------------------------------------------------------------------------------ Shape the Mobile Experience: Free Subscription Software experts and developers: Be at the forefront of tech innovation.
