This depends on whether you are an "expression style" or "declaration style" programmer. http://www.haskell.org/haskellwiki/Declaration_vs._expression_style http://www.haskell.org/haskellwiki/Let_vs._Where
Reading the let vs where page I'm left with the strong impression that I should use let everywhere. I know that's not true, and in fact I much prefer where. Can we put a Wikipedia style "NPOV" (neutral point of view) tag on that page? Or can someone do some editing?
Maybe it would be enough to represent the example "where" problem more fairly on its own terms. The non-working example has us writing f = State $ \ x -> y where y = ... x ... but the "where" side of the aisle is supposed to detest lambdas, so would be unlikely to have taken this particular route anyway. I'm not saying "ergo, there is no problem after all", only that it's not all that well taken. Donn Cave, donn@drizzle.com
