Dear all,
I've recently thought of a possible syntax extension for (Perl5's)
[un]pack() and I posted my "RFC" to clpmisc where it didn't have much
success, I must say. However I'm not interested in proposing it here, only
I would like to investigate a possible Perl6 technique inspired by those
I was thinking about removing files this morning, and realized that I
wish rm supported inclusion/exclusion.
In particular, I wanted to remove "* but not Makefile" (since my
Makefile uses lwp-download to re-fetch the source code, etc.)
It occurred to me to wonder: can P6's c do the same thing?

Well, you can, depending on your shell:
in ksh: rm !(Makefile)
in bash: ditto, but you have to turn on the "extgl

Judging from this, maybe we ought to have :not.
Anyway, it's still possible:
$my_rex = rx/fo*/ & none(rx/^foo$/);
For sure. On a side note, there should be a negating match operator for
use inside:
rx/\d+/ & none(rx/1984/)
could get awfully long if you had to handle sev

Of course, the regex itself can do

Assuming Perl 6 has a "pack", which it may not:
for @t {
$result

What is the second set of parens for? Will the following suffice?
rx/ (fo*) { $1 ne 'foo' } /
And it is because of the lack of anchors that this won't work as
expected?
rx/ fo* /

Er, at the moment bare closures don't care about their return value,
so as it currently stands, you'd want something more like:
rx/(fo*) {fail if $1 e

Bare closures are used only for their side effects

I know: this is one of the reasons why I wrote (hopefully *clearly*
enough) that I was just using it as an example. A user defined pack()
whoud do just the same here, anyway.
