It's just a different style of working, but I almost never type long symbols. I go to their definition site, yank them into a buffer, and paste them into place.

It's just a different style of working, but I almost never type long symbols. I go to their definition site, yank them into a buffer, and paste them into place. Or, I work with a REPL. So I write the code there and run it before putting it into my code base, so I know it's correct.
