This makes sense if you're dealing with some form of compression other than "gzip", or if your dealing with multiple types of compression (i.e. part of the process is to verify what sort of "$unzip" and "$unzip_opts" are needed).

If you were just dealing with a distinction between plain files and gzipped files, then you would want to use the Compress::Zlib module, or better yet, the PerlIO::gzip "layer" in Perl 5.8 -- this could simplify things a lot, to the point where you might not need separate subs for opening files and doing line-oriented IO (check this little node for a quickie sample of PerlIO::gzip in 5.8)

UPDATE: (2010-10-18) It seems that PerlIO::gzip should be viewed as superseded by PerlIO::via:gzip. (see PerlIO::gzip or PerlIO::via::gzip).
