I think that roboticus is "on it"!

From my experience, the coding efficiency of Perl vs C is in the range of 3x-10x:1. Recoding a 5 page C program into a one page Perl program that achieves the same functionality would not be a surprising result.

The Perl program will run at something like <1/3 the speed of the C program, but often (and VERY often), this does not matter at all! Perl OO vs say C++ is a different thing and it has an additional performance penalty.

My only slight "nit" with this would be about assembly. In the past decade, the C "super optimizing" compilers have become so good, that you have to be a real guru at ASM to beat them. It is possible to do for very focused tasks, but it is certainly not easy! Some folks can actually wind up writing slower ASM code than the compiler can do.
