i ask b/c i was thinking it would be good if def actually returned a value, i.e. the symbol of the method being defined.

def foo # => :foo
...
end

why?

private def foo
...
end

instead of having to do seperated way.

I can already open my EXE from Ruby using:

IO.popen("gui.exe")

I'm hoping that I can remove the chrome from that EXE before I run it...

... either at runtime with some command or option...

... or before I run it if there's some place in the binary file I can change
something...

... it might even be ok if I had to embed the exe in some other exe... as
long as I could still give everything to the client in 'one exe'...

... is there a simple way?

Thanks!

P.s. - I'm really, really clueless about any serious programming, so please
go easy on me if it's simple... thanks!

I did some more thinking on my initial suggestion and came to the
conclusion that def should return a Method which like all other Methods
should have a #to_sym.

It sure would be nice to know what matz thinks about all of this!

Yes. Would you add it, Mike? Or Dave?

In the RubyConf keynote talk, Matz indicated that Ruby 2.0 would return
/something/ from a def. I don't recall if he was specific about what
that something was.
