simplifies a regexp
We simplify two things here: First since * is greedy it is enough to go
look for the rightmost ::, no need to ask the regexp engine to match the
rest of the string since we are not validating anything, only capturing.
The second simplification comes from using a look-ahead assertion, that
allows us to have the capture in $&, thus removing the need of a group.
