It does not invalidate anything I have said, and this reasoning of yours is so flawed.
For example: I thought this or that music or movie sucked. I do not need to know how to make a song or a movie to be able to criticize it, let alone have one in a similar vain, same with books. I can criticize a book, or an article, without having written one myself on related topics.
All that said, where did I criticize? I did not criticize anything, at all.
I stated facts. Perl is indeed faster than Python, and Perl was indeed made with string manipulation in mind. I made no comment about this project or its author, thus, it was not a criticism of any sort.
