Even that is not correct.

- Perl thunks some functions directly to the C api.
- C doesn't have native support for some features native to Perl (maps,
regexs, etc), so you will need to either create one or use an existing one.

Since those implementations might be slower than the Perl equivalent, you
might end up with a slower program. Perl has had a lot of fine tuning, so
you are going to have to do a lot of work (say use ASM, not C) to generate
faster code.

Importantly, Perl allows for rapid protyping - which (generally) cant be
said for C.

So while "choosing the same algorithm" for both languages might expect C to
be faster, it doesn't make it so, and indeed rely's on your ability to be a
better programmer than the language/library writers.
