A statement like "var F = Foo" can't work if Foo is a generic function. What would be the type of F? All generic functions and types must be fully instantiated at compile time. "var F = Foo[int, int]" does work on the head of the dev.go2go branch. Ian -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
