Perl/Python Advantage is not Dynamic Typing

The latest entry into the strong/dynamic typing debate comes from Dave Copeland. He does make a good point in that Perl and Python have many features other than dynamic typing which make them faster to program in. I think he misses something when he talks about code being skipped in unit tests because there isn’t time. For those of us doing test driven development, the tests come first! The only code that I don’t write tests for now is code that is really, really onerous to test, and there’s not much of that. And where it does exist, I try to isolate it as much as possible.
