So, Python regexps are suddenly more readable, even though they need
additional layer of backslashes?
$_ does not rely on unreadable style. First, it's a common idiom, so it's in
no way less comprehensible than list comprehension in Python. You just need to
understand what it means. Second, it's not an obligation to use $_. I often
avoid it if it doesn't make my code reflecting my intentions better. Funny
thing, I do the same in Python, C, and Erlang.
And I hear about $_ and regexp literals as unique selling points (if I read
your acronym correctly) only from people that don't really write in Perl.

Python encourages a style that makes less use of regexps. (And you don't need extra backslashes, you can use r'...').

Nice ad hominem. Go on then - what's your USP for Perl? Why should one use it over Python/Ruby/...?

Yes, even in the places where regexp would help very much. And even if you'll
insist on using regexps, Python makes them highly inefficient or cumbersome
(or both), because if you're careful, you'll either get code that needs to
store compiled pattern somewhere vaguely related to the code at hand, or code
that compiles the pattern on every use. If you are not careful enough, you'll
get the two at the same time.

Thank you, though I wasn't refering to yourself. It was pretty clear you don't
write Perl much.
My reason to use it is because it was my primary language for over a decade.
For other people? I don't know. All three are similar in what they can do and
how does it look afterwards, as all of them are scripting languages in OOP
land.
Combine that one and Perl's learning curve, and you'll get why Perl usage was
declining over the last decade.
