The letter ℘: name and origin? (2017)

Googling for "Math squiggle that looks like a cursive P" is not a very elegant or convenient way of learning new symbol names.

I wish every proof or equation came with a little table that gave the English pronunciation and some context for each symbol used.

It would make it a lot easier to look up tutorials & ask questions.

A word is easy to search, but something like “~~>>=>” doesn’t really give anything and it’s not nearly as cute as the writers of the libraries seem to think it is.

I know about Hoogle but that’s not a solution, as that only searches documentation, not stuff like Stackoverflow.
