Slowly coming to the conclusion that named arguments are a good thing. Contrast: Either.cond(foo, bar, baz) With: Either.cond( test = foo, right = bar, left = baz )

I agree, though Either isn't ordered that way. For no better reason than the two words (with different meanings) "right" and "right", happening to be spelled the same way, we decided to put the unhappy outcome first in Either.

Did we? I assumed we copied Haskell's practice. And in Haskell what came first: punning on Right=right or using Right for higher-order unification?

I have Martin on record saying it was copied from Haskell - by correcting me in the middle of a talk, which was a bit embarrassing. There might have been further comments along the lines of "I don't like Either, Try is much better, and we really should have used Result instead".
