Perl 6: language has "local" variables (ie "dynamic" vars)?

[David Combs]

In a bookstore a few days ago, looked at 2nd edition
of Perl 6 (O'Reilly).

Saw dynamic vars in the interpreter-language, but
no mention in the perl-6 language.

Is it there? Better, does perl-6 have such a dcl?

For when it's needed, is very nice indeed;
saves having to write lots of exceptions-code.

Thanks,

David

I'm not sure if I understand what you mean. AIUI Perl6 will finally
get rid of the two current mostly orthogonal sets of variables
(pacakge and lexical). What is now C<local> will be C<temp>. But then
since you talk about exceptions, you may also be interested in
hypotheticals, continuations and other marvels...

Great! So it'll now be called "temp".

(I would have preferred "dynamic", which is what common-lisp
calls it, the pre lexical-concept of variable binding used
in pre-common lisps, and still used in emacs-lisp.)

Thanks!

Don't forget Perl's intrinsic and typical
natural-languages-likeliness... IMHO "dynamic" wouldn't have been just
as intuitive, and by far!


PS: anser if you like, but then take into account that most probably I
won't be able to read news for one or two weeks or possibly even till
September!
