Thanks. Do you have any idea how much worse it is?
I ask because I have some old scripts that go spinning thru the whole
hash in that same way, that I should probably track down and change

I meant regular expression delimiters .. often `//'

How does it differ?

I guess I should have asked why is it incrementing that data and why
is $r2 in squiggly brackets?
