Is there a way to shorten the following mostly concerned with why I
have to use a temporary variable.
Unless you have some reason to store the intermediate results you can say:
@list = map { s/\s+/_/g; $_ } grep { /\d/ } <FH>;
But this is probably a bad idea; generally speaking, file handles
should not be put in list context.
