in thread Regexp generating strings?

For Perl regexes, its seems rosy until you reach look-aheads. /^(?=$rx1)$rx2/ needs to find the intersection between the two languages defined but $rx1 and $rx2, if it exists. Without the ^ anchor $rx1 is floating in $rx2, it becomes substring instead of intersection.

It may be solvable, but not by me.
