My understanding is that this died with 5.10. Is that right?

Do you know Perl 5's $& variable? What you want isn't exactly new for
Perl.
In Perl 6, the match object $/ will instead be used. It's a bit hard
Think about adding \& to the replacement part of a s///.
As in sed, the & means the whole match.
Then one can do
s/$search/*\&*/go
in stead of
s/($search)/*\1*/go
and there needs to be no $1 variable set up.
(I assume that using () always makes a $1 available, even if it is not

IIRC, flip flop will not return as the ".." operator. Also, the global

We've had several discussions of .chars and .elems, and I said
something about objects in certain contexts.
In the discussion about objects, I left item and list context out,
because in those contexts, always the object is just itself.
One thing makes .chars and .elems look symmetric: they are bo
