ghci also gives you a list of names if it can't find the variable you typed wrong. I'm not certain but i assume they use Levenshtein aswell. I definitivly use Demarau-Levenshtein for the same feature in pjass.

GHC also uses Demarau-Levenshtein [0]. The fuzzy lookup function gets re-used for a couple places too (including whatever you encountered in GHCi).
