Lets see the code? Regex has always been a Perl selling point, and you're just benchmarking the Python Regex library (written in C) against Perl's regex library. That's not a fantastic basis for a comparison.

Perl 5: #!/usr/bin/env perl use 5.026; open my $fh, ' ) { chomp; say if /\b\w{15}\b/; } close $fh; Python 3.8 #!/usr/bin/env python import re with open('logs1.txt', 'r') as fh: for line in fh: if re.search(r'\b\w{15}\b', line): print(line, end='') Why isn't it a fair comparison? The startup time is generic and string parsing is a major feature of, say, web development. I didn't say Perl5 numerics match Python's but e…

For many years Perl subroutines didn't even have method signatures so you had to unroll @ on the first line of every sub. I think even today it may still be considered experimental. Jeez!

Yeah it's pretty archaic. Shortest hand way of doing it is like this: sub method { my ($self, $a, $b, $c) = @_; } $self being a reference to the current module (ala Javascript's 'this')

They last line of the article summarizes it well: > Perl 7 is v5.32 with different settings. Your code should work if it’s not a mess. Expect a user release within a year. Are there actually people that are still deploying new things in Perl? The only times I see it is for legacy stuff, and then only because the script is too much of a hassle to be rewritten.

I used to work for a company that used Perl as their primary language. The codebase was millions of lines long, modules (pm files) with like 1000 methods and 10,000 lines, a total mess and it had 0 unit tests too. Almost beyond salvageable. Left a bit of a sour taste. They're trying to migrate to AWS but AWS don't even natively support Perl in their libraries. There's a few third party libraries in CPAN but nothing a…

Perl used to have one of the most extensive module libraries. One of the things I miss about Perl was it’s more sensible module namespace convention (Eg Net::... for networking related) vs the more hip but confusing and hard to discover naming of node modules.
