The more I learn about Perl, the more impressed I become with the performance. Perl codes at about a 3x-5x and sometimes 10x efficiency in terms of source lines vs 'C'. From what I can see, great Perl code runs like 1/3 the speed of average 'C' code which given the coding efficiency is just fine - actually Great! I have become a fan of Perl.

I am curious as to the implementation of splice() in Perl. Does a splice() really result in a copy of an entire array, like a typical 'C' realloc()? If a Perl array has say 1,000 elements and I do an "insert" after element 2, how does the low level Perl deal with this? Does it really do 1,000+ operations?

How does Perl handle the push or unshift operations?
