RE: [Haskell-cafe] Small question

| And, of course, if it's a strict argument, then the values stored are | ALWAYS one of two possibilities. So as a matter of curiosity, would | there be any advantage at all for "unboxing" enumeration types? (Apart | from, I suppose, the possibility of using fewer than 32/64 bits to store | a flag.) Possibly some, but less now because of pointer tagging (see paper on my home page) http://research.microsoft.com/~simonpj/papers/ptr-tag/index.htm. We've never gotten around to unboxing enumeration types because we couldn't convince ourselves that the win was big enough. My nose tells me there is probably a small win, but whether it's worth the additional complexity I'm not sure. S
