	A guru I spoke with says they are effectively untouchable. I also
was wondering why they didn't show up with '-re'. Turns out they go out
of scope _fast_ after the pattern match - as soon as the current code
block ends, even from e.g. within if(){ }.
	It may be possible from XS, but it would likely be ugly.
