in thread How do I extract named variable names from regex string
Sorry for nitpicking, but in praxis this only works with a string where all groups match, "" isn't enough.
use 5.010; "" =~ /(?<mon>\w+)\s(?<mon>\w+)/; print scalar keys %-; # 0
Now constructing such a string is in general even more difficult than just parsing for named captures labels.
Good idea anyway! :)
Cheers Rolf
