Unfortunately that is not possible because every part of the
expression is pretty context sensitive. I'm trying to match From
and Date headers against RFC 2822 correctness. My Date expression
is 1000 characters long, the From expression is 1150 characters.
I could test twice and match against one alternative at a time
(there are several alternatives in the expression), but that would
make me split up the regular expression that I so carefully
crafted. :-S
Well, thanks anyway, I certainly won't mess with the code!
