As i said: it isn't perfect yet. ;) But maybe one of you could 
help me.
And regex are the only way i know to scan code.
And yes i know, sometimes warnings for unused variables _would_ 
be annoying but then we have to discuss if a new compiler switch 
is useful.
IMO it is, but IMO a shorthand like "?" for not null types is 
similar useful.
Maybe i expect to much, maybe i should use such programms only by 
myself.
