Proposal: add fromRight and fromLeft to Data.Either

[Theodore Lief Gannon]

js :: a -> (Void, a)
js x = (undefined, x)

left :: (Void, Either a b) -> a
left (_, Left x) = x

There we go... now it looks truly terrifying:

left.js $(myValue)


(Apologies to Kosyrev for the double-send. Especially since that version
was broken.)
