in any case, i think we have a fair agreement on rfc 158 and i will
freeze it if there is no further comments on it.
I think you should remove the parts of your propsal about making $ be
autolocalized.
If you're not planning to revise your RFC, let me know so that I can
ask the
(mystery: how
can filling in $ be a lot slower than filling in $1?)
It isn't. It's the same. $1 might even be more expensive than $.
It appears that many people don't understand the problem with $. I
will try to explain.
Maintaining the information required by $1 or $ slows down the

Heh. I once complained about the lack of such an array, in
