I understand that. The problem, is that this kind of interpolation is really
simple and may happen regularly, so it would be great to be able to write it
in a way or another (even if it requires to use a non-perlish trick, since
perl is no help there). As I said before the following substitution string
happened to work in this case:
"$1\\2" (instead of "${1}2"}
Is this a normal behavior (as I stated I failed to make it work with perl,
but nobody's perfect) or a transient bug in the escaping process ? I tried
it with former versions (1.1 and 2.0) and it didn't work.
