> Someone using Perl for scientific computing makes it harder for others to collaborate on the project Just to the other people that never have the ambition, desire or toke the time to develop new valuable skills. This is not a bad thing necessarily. Those people are time sinks. In any case you can take the decision to document or not your code in any language. "; # this line does that" is not hard to write. And different science teams collaborate, but also compete for money. So everybody doing the same can lead to "the more dishonest takes all" and kills all the other teams. Sometimes is useful to protect yourself from the people trying to backstab you and steal your best tools. Tools that toke you decades to develop and polish. Not ALL is freely shared in science. And yes, my Perl scripts were a triple headache to write, but still work flawlessly after all this years. Perl is just a tool to do something, and you should never use one (and the same) tool for everything unless your goal is to be a mediocre scientist sucking from other people's efforts all the time.
