That will be slower though.

The reason I suggested it is in case someone wanted to use your SuperSplit with tied filehandles. I would not depend on a tied filehandle correctly paying attention to $/, so the join makes sense.

But if you care about performance or have good reason to believe that people won't use tied filehandles, then avoid join.

    For the best of both worlds, use both:

    my $contents= do { local($/); join '', <INPUT> };
    should work quickly for file handles that pay attention to $/ and work about as quickly as possible for those that don't.

      Modified davorg's code accordingly. Some improvement, clearly:
      Benchmark: timing 50000 iterations of hybrid, join, slash... hybrid: 4 secs ( 2.90 usr 0.38 sys = 3.28 cpu) join: 6 secs ( 5.65 usr 0.35 sys = 6.00 cpu) slash: 3 secs ( 1.95 usr 0.38 sys = 2.33 cpu)

      I was dreaming of guitarnotes that would irritate an executive kind of guy (FZ)
