LSP will let you know, but to provide a counterpoint... The type that the function should take may not be the concrete type, func myfunc(file ...) might be func myfunc(f *os.File) or func myfunc(r io.Reader) or any of a number of other interfaces that *os.File satisfies. The choice here is not necessarily defined by the type, but more by the intention of the programmer. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
