5857	proto::function undocumented for use in grammars	John Maddock	Eric Niebler	"There's no documentation on what template argumentes proto::function takes when defining grammars.

Also it appears that proto::function enables the function call operator for protoized types, as well as being used by functions that need to return lazy expressions.  This dual use and how to restrict or prevent function call operator overloading should also be documented."	Bugs	closed	To Be Determined	proto	Boost 1.47.0	Problem	fixed
