[Lazarus] Forward procedure completion failure

[Lubos Pintes]

Hi,
Just wanted to try the cool feature, adding a procedure body to 
implementation. So I wrote a procedure header, pressed Ctrl+Shift+C, and 
found this in a message window:
uiacore.pas(9,1) Error: unknown section keyword interface found
I tried to compile, and only errors there are two unresolved forward 
declaration, those I just wrote.
Isn't this weird?
