As one of the two or three people in the world who think that Ruby's
scoping rules are actually fine, I have to say that after all this
debate, people had better use whatever the new thing is, whether it's
necessary or not!  :-)

And I suspect people will, which means that if we have "local {}" or
"let x = ", we're going to see *lots* of them.

Which, in turn, makes me reluctantly think that it would be better to
have local be the default, and some way to explicitly import variables
from outside the block into the block.  I think the impact on the
overall look of Ruby would be enormously less.

Not that I have any great ideas as to how this would be notated... but
whatever it is, at least it would appear less frequently.
