Yea, I think that will be a better solution. The only point, after I've opened the file, that I actually care if it's a file is the overall while loop, so as long as I start that loop with an open filehandle or an IO::File object, I can just do the while loop on it:
while ( my $line = <$current_file> ) { ... } # $current_file can be a filehandle or an IO::File obejct # or anything else that responds appropriately in the < > # construct.
Besides making that change, I think I'll also closure-off the internals of that loop; it will be much easier to write the other suggested functions that I put in the desc of this code; in addition, I can see an 'fmap' function and a few other things that as long as I have a function that determines what you do with a line, it doesn't matter what else goes on.
