In that case, if myLocalMethod can only be visible from myMethod, can
we say the receiver responds to myLocalMethod message, or not?  I am
afraid such "local methods" risk break the language's object system.

It's much easier to make such inner def to define a singleton method for
the receiver, and I have ever considered it, but I didn't get
confidence on the idea.

|2) Procs without proc keyword.

|Is there any reason why we need a proc keyword in front of a block?

This idea has risk to break the syntax.  Making keyword less braces a
block conflict existing syntax (a lot).  The idea should be realized
in the different language, I think.

p.s.
Try not to change the language first.  Try bend it.
