Is there any plans to implement public procedures/function of a class that can be used without been necessary to create the class?

Do you know class procedures/functions?

=== example begin ===

type
   TTestClass = class
     class procedure Foo;
     class function Bar: LongInt;
   end;
class procedure TTestClass.Foo;
begin
end;
class function TTestClass.Bar: LongInt;
begin
end;
var
   x: LongInt;
begin
   TTestClass.Foo;
   x := TTestClass.Bar;
end.

=== example end ===

Regards,

does

class procedure foo(bar: TSomething);

not work ?

I presume you know about class methods such as TObject's

class function ClassName : shortstring;

that you can use like this

procedure TForm1.Button1Click(Sender: TObject);
begin
   ShowMessageFmt('Class name of TEdit is %s', [TEdit.ClassName]);
end;

without needing to instantiate a TEdit instance?

Those already exist. They are called "class methods". See http://www.freepascal.org/docs-html/ref/refsu27.html

This exists: class functions.

Given the declaration

  TMYClass = Class
    Class function doGLobal (Arg : ArgType) : Resulttype;
  end;

Then

TMyClass.doGlobal(a)

Is Valid.

Exactly that i was meant, thank you people.
