Re: [Haskell-cafe] Why isn't pattern matching lazy by default?

Now why isn't pattern matching lazy by default? This seems odd for a newbie since everything else is lazy by default.

It's even more confusing that pattern matching in 'let' _is_ lazy.

No, it's not. See, in let or where constructs you don't have a choice; you can't do different things depending on whether some value is Just x or Nothing. Therefore, there is no need to perform pattern matching strictly.
