You're not binding $2:=$1. You're binding $2 to the first
capture. By default $1 is also bound to the first capture.

Zero. No explicit captures in that pattern.

Agreed. For a start, it's too late. The declaration is compile-time;
the assignment, run-time.

Urgh, no. Either a pair is an atomic entity or it isn't.

Yes, but this:
my Really::Long::Package::Name::Ugh $date is now {.init 'June 25,
2002' };
Is shorter

I don't think \n can be a character class because it
is a two character sequence on some systems. Apoc 5
said \n will be the same everywhere, so won't it be
something like
rule \n { \x0d \x0a | \x0d | \x0a }
Hmm.

The problem is that unmake_COW will always resize the allocation down
to bufused (plus the padding added by mem_allocate). This means that
the buflen test could pass, and
