No. There is no such thing.

The standard answer to this in the Perl FAQ (old versions) was:

2.32) How can I convert my shell script to Perl?

Larry's standard answer for this is to send your script
to me (Tom Christiansen) with appropriate supplications
and offerings.  :-( That's because there's no automatic
machine translator.  Even if you were, you wouldn't
gain a lot, as most of the external programs would still
get called.  It's the same problem as blind translation
into C: you're still apt to be bogged down by exec()s.
You have to analyze the dataflow and algorithm and rethink
it for optimal speedup.  It's not uncommon to see one,
two, or even three orders of magnitude of speed difference
between the brute-force and the recoded approaches.
