I admit I'm confused by this.  Is 'local' being introduced?  And if
|a| is a block variable, isn't it local to the block anyway?

I'm not sure what you mean.  Do you mean what would I do if I were
designing Ruby 2.0, or what do I think Matz will have them do?  I
don't know, since I still don't know the answer to the above (whether
Proc and lambda will be different in this respect).  I think maybe you
think that I know, but I don't :-)
