Definitely.
Lisp is like that, it allows you to do things that are impossible in other languages.
You just need to write some code and BAM, you have a scraper. Try doing that in Perl or C or some shitty pleb language.

Yes you want programs.
There's none. Fuck you.

I could rewrite https://dis.4chan.org/read/prog/1377844099/1- in CL.

Can it mix?

symbol1.symbol2.symbol2...

(*dot* symbol1 symbol2 symbol3 ...)

Let's do it right now in common lisp. Implement it as a reader macro and give some meaning to the please-dont-use-this-package:*dot* symbol.

100 points if your solution uses dynamic hashmaps

10000 points if your solution uses vectors that evaluate the symbol keys at compilation time and use type inference to map them to constant indeces based upon the type of symbol1
