[regex] \&

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
being used.)
