I'm trying to be a good boy and reuse regular expressions from the
Regexp::Common world (ultimately $RE{time}{american}).  I have things
working, but as I was playing around in the debugger I discovered
something "funny".

It seems that any time I try to touch %RE I get an error, sometimes
things Go Badly enough that I end up back at my shell prompt.

It blows up with pretty much the same message in 5.14.2, 5.14.3 and
5.16.2 on a current Mac OS X system.

This doesn't seem to keep my code from working but it smells funny....

Can anyone shed any light on what's going on?
