Historically (not today) C++ programmers were far less likely to ever write a test to make sure if (line == "" || line[0] == '#') continue; does what they think it does than the Perl programmer was to write a test to make sure next if (/^(#|$)/); does what they think it does. The C++ programmer was far more likely to eye-ball it. This is a simple, historic fact. TDD came to Perl before it came to C++. I am making a simple statement about actual practices, not some kind of larger point. TDD came to Perl earlier. simple fact.
