Hoogle allows you to search many standard Haskell libraries by either function name, or by approximate type signature. I find it very useful. Is there anything like Hoogle for Scala? Search in ScalaDoc 2 only finds types and packages by name.

Now, I've actually implemented it but am wondering wether there exists some standard alternative, because it seems to be…

In Monads for natural language semantics, Chung-Chieh Shan shows how monads can be used to give a nicely uniform restatement of the standard accounts of some different kinds of natural language phenomena (interrogatives, focus, intensionality, and quantification). He defines two composition operations…

('T -> bool) -> 'T list -> int
ie, something that counts how many items of a list that a function returns true for. (or returns the index of the first item that returns true)
I used to use the big list at the MSR site for F# before…
