As a once and, who knows, maybe future Perl dev I find it a weird choice of grouping, no disrespect to Fortran, but I also think there are probably quite a few mature Perl codebases tended by mature Perl programmers who have their ergonomics and ease of use very dialed-in. Whether you would enjoy it is a different question, but my impression from years of doing Perl is that the most committed hackers tuned their environments and organized their projects just so, and would laugh at anybody else’s idea of “ergonomics.”
