[fpc-pascal] "class" methods for objects

[Michael Van Canneyt]

It exists already, but is called 'static'

program testso;

Type
   MyObject = Object
     procedure MySomething; static;
   end;

Procedure MyObject.MySomething;

begin
   Writeln('OK');
end;

Var
   O : MyObject;

begin
   O.MySomething;
end.
