Re: [Haskell-cafe] Pattern matching with where free variables can be used more than once

Christopher,

Wouldn't it be great if pattern variables could be used more than once in a pattern? Like so:

foo [x,x,_,x] = "The values are the same!" foo _ = "They're not the same!"

These are called nonlinear patterns. I think Miranda (a precursor of Haskell, sort of) used to have them. Cheers, Stefan
