Re: patterned functions: you can't rely on patterned functions in a full-featured IDE that allows any class method to be an event handler/delegate for another class instance. What you end up may look like what Delphi is doing, but it is just an approximation of the real thing that won't work very well for general-purpose usage. There's going to be all sorts of edge cases that don't work correctly because you can't get a reliable signature for a given method.
