in reply to better way to escape escapes

Often better to do such things in a single pass.

s{[\\@]([\\@]|[_A-Za-z]+)}{ my $term = $1; if( $term =~ /[\\@]/ ) { $term # Replace repeated escapes with second of pair } else { print "Extracted code '$term'\n"; '' # Replace extracted codes with nothing. } }ge;
