I want to reduce following to substitutions into one, is that possible? 

# convert medial capital into capital separated by "_"
$str =~ s/([a-z]+)/sprintf(uc($1)."_")/ge;
$str =~ s/_$//;

"g" matches globally, eg. if I have "camelCase" then first substitution ends with "CAMEL_CASE_". I want to save 2nd substitution. Names can be any length in runtime, ie. such as "namesCanBeDifferentAny" etc. Is there a way to stop regexp engine in the (n-1)th match, providing that there are n matches?

In reply to global match except last one by utku
