Subject: Re: Proc.class vs yield

That's a slippery slope to smalltalk ;-).  I suppose you could if you were
required to give an empty arglist like [|| ...] when there weren't any
arguments so there would be no confusion with an Array literal.  But if you
were going to change the language why not only allow one of the two currently
allowed syntaxes for a block ({|| ...}, or do || ... end), and use the other to
instantiate an actual Proc object (and I'm not necessarily advocating this, but
it might add more visual distinction).  The best I can offer you is a band-aid,
lambda instead of proc (a much nicer word don't you think?).
