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 cbut do the same

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

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

That is, can I say:

The word junction came to my mind as I read your mail.
$my_rex = qr/fo*/ qr:not/foo/;
Of course, the regex itself can do this:

qr{(fo*) ({$1 ne 'foo'})}
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/ !before foo 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

Bare closures are used only for their side effects
