Subject: Re: new block notation

Just a random thought.  If we can't do fun(...) { ...}
because we can't add a new keyword, what about this?

   make_counter = do(start=0) { do { start += 1 } }
   counter = make_counter[5]
   5.times { puts counter.call }

I haven't considered backwards-compatibility, or much
anything else for that matter.  It just occured to me.

Of course, it would prevent this

   foo.find lambda { default } do ... end

so you'd have to put in parens:

   foo.find(do { default }) { ... }

(In general, you'd need parens around any literal anonymous
function passed to a method.)

I don't know if I like it.  At least it's shorter than both
`lambda' and `proc', and looks less line-noisy than `->'.

    So really, we all have to ask ourselves:
    Am I waiting for RMS to do this?   --TTN.
