Re: [Haskell-cafe] AND/OR Perceptron

I suppose I wasn't entirely clear. "where" is syntactic sugar for "let...in", pattern matching is syntactic sugar for "case", and guards are syntactic sugar for "if..then..else" and/or "case" (for pattern guards) In fact, the whole reason for the existence of "where" is so that it can attach at a higher-level scope and make use of the other syntactic sugar (like guards). Also, I find the postfix definitions in "where" to generally be more readable, but that is a matter of taste. -- ryan On Sat, Oct 31, 2009 at 11:33 AM, Chaddaï Fouché wrote:

"where" is just syntactic sugar for "let...in"

That's not perfectly true : "where" and "let...in" don't attach to the same syntactic construction, "where" attaches to a definition and can works for several guard clauses whereas "let ... in expression" is an expression in itself.
