When you first put forward this argument (specifically with regard to av_len), it made sense to me, and I had no objection to it. Later, people wrote to p5p complaining that the new situation was more confusing; in addition, *I* started to get confused. That was when I started to have second thoughts. I think Damian Conway was right when he wrote in PBP that one should not use English (the module). Since other people use punctuation variables, you are going to have to learn them anyway. Using the English names just forces others reading your code to look up the names that you are using. It just creates more cognitive burden. I think the same applies even to poorly named functions. You just have to learn the gotcha once, and then you can use the function and read code that uses it. (And if you use functions without reading either the documentation or the source, then you are coming close to what I would call autopodotoxy.) > Unless Perl is close to death, the number of people who are going to > come along before it does die dwarfs the number who are already > expert. > Some people are knowledgeable in parts of Perl, but not all.

Not to mention a lot of existing (and correct) code that they cannot read without learning the discouraged parlance. So they have to learn the different forms anyway. My personal experience is that what you are arguing for, while it sounds good, does not work in practice. -- Father Chrysostomos --- via perlbug: queue: perl5 status: open https://rt.perl.org/Ticket/Display.html?id=131685Thread Previous | Thread Next
