} perl has a similar feature.
Wouldn't it have been better to put these in the $match array (or into
some other named array) the way that backrefs in glob patterns do?
$1 etc. in Perl are not positional parameters -- you don't lose access
to @ARGV when you do a pattern match. I think clobbering the positionals
is more harmful than helpful; if you want to be able to reference $1 etc.
you can always do
pcre_match ...
set - "$match[@]" # or whatever it is named
For comlete generality, pcre_match could take the name of the array to set
as an argument; then the above could be accomplished with
pcre_match -a argv ...
(where I've chosen -A somewhat arbitrarily, and another character might be
better).
