dep has covered the downside of
$&, but on your
split question, the beauty there is that you don't need to match
the (sometimes) complex target of your interest, just the separators that mark where
your interest ends, and that's often a lot easier. In this case, if you're going
to verify the date anyway, there is not much sense in going to great lengths to
do that in the regex, so you can just
split on whitespace instead.
As you noted, split
won't be able to find your dates at all. It is a great option if you
are parsing some sort of log file in which the lines always start with that date
format, but if you want to get that date out of the middle of a lot of other text,
a specific regex would be my choice, and instead of split you can use $1 etc. to
get your date components, like:
if /(\w{3})\s+(\w{3})\s+(\d+)/){
($day, $month, $daynum) = ($1, $2, $3);
}
Finally, while we're talking about OWTDI, you might also consider
unpack
for jobs like this as it is usually faster, though it is even more fussy about
the format of the data being consistent. It is however ideal for fixed-width columns of data
(anyone else still dealing with data in card images?).
