Thanks very much for the code sample and link to Bernstein's great RFC
822 info site.
No problem.
I would like to point out that your code can be improved by replacing
uses of $& and $` with parentheses in the regexes followed by $1 and
$2. This is from the Devel::SawAmpersand doc . . .
I was unaware of this issue; thanks for bringing it to my attention.
But Devel::SawAmpersand doesn't really explain the problem in any kind
of depth, and just talks about "massive in-memory copying." So,
presumably, this is just a question of efficiency?
