# Alternative f => [f a] -> f a -base -fgl

Randomly uses one of the given generators. The input list must be non-empty.
The union of a list of maps. > unions [(fromList [(5, "a"), (3, "b")]), (fromList [(5, "A"), (7, "C")]), (fromList [(5, "A3"), (3, "B3")])] > == fromList [(3, "b"), (5, "a"), (7, "C")] > unions [(fromList [(5, "A3"), (3, "B3")]), (fromList [(5, "A"), (7, "C")]), (fromList [(5, "a"), (3, "b")])] > == fromList [(3, "B3"), (5, "A3"), (7, "C")]
The union of a list of maps, with a combining operation. > unionsWith (++) [(fromList [(5, "a"), (3, "b")]), (fromList [(5, "A"), (7, "C")]), (fromList [(5, "A3"), (3, "B3")])] > == fromList [(3, "bB3"), (5, "aAA3"), (7, "C")]
The union of a list of sets: (unions == foldl union empty).
Push the current matrix stack down by one, duplicating the current matrix, excute the given action, and pop the current matrix stack, replacing the current matrix with the one below it on the stack (i.e. restoring it to its previous state). The returned value is that of the given action. Note that a round-trip to the server is probably required. For a more efficient version, see unsafePreservingMatrix.
A more efficient, but potentially dangerous version of preservingMatrix: The given action is not allowed to throw an exception or change the current matrix mode permanently.
On Windows operating systems, the networking subsystem has to be initialised using withSocketsDo before any networking operations can be used. eg. > main = withSocketsDo \$ do {...} Although this is only strictly necessary on Windows platforms, it is harmless on other platforms, so for portability it is good practice to use it all the time.
O(min(n,W)). Delete the maximal key. An error is thrown if the IntMap is already empty. Note, this is not the same behavior Map.
O(min(n,W)). Delete the minimal key. An error is thrown if the IntMap is already empty. Note, this is not the same behavior Map.
O(n). The reverse of a sequence.
O(log n). Delete the maximal element.
O(log n). Delete the minimal element.
Join path elements back together. > Valid x => joinPath (splitPath x) == x > joinPath [] == "" > Posix: joinPath ["test","file","path"] == "test/file/path"

censor f m is an action that executes the action m and applies the function f to its output, leaving the return value unchanged. *  f m = pass (liftM (\x -> > (x,f))
