Instead, in the kdb team I joined recently (a one-letter, symbol heavy language used by quants), nobody can remember what things do, nobody has time to teach you the insanity of code older than 2 months, and you re instead spending weeks "learning" under the heavy sighs of everyone suffering from the new burden guy.

Why do you want to do things compactly rather than with clarity?

I wish google could search for one-letter language specific symbol so I could ask "what does -9! do on type J vs type C" (nonsensical exemple, I cant remember types without looking at the type table, but I think -9! transforms a bit array into an object)
