          Issue ID: 19379
           Summary: Make a public alias for the return type of
                    std.typecons.scoped
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: phobos

The documentation for std.typecons.scoped says to use typeof() to identify the
type.

I know the arguments for keeping the actual type opaque. We've been over it
with std.regex.Captures and so forth. It would be really great to have a way to
name that type succinctly so you can use it in fields, pass it as a parameter
(by reference obviously), instantiate templates of it, explicitly name variable
types, that kind of thing, without having to use aliases everywhere.

Example of someone getting confused by how to use it without that sort of type
naming: https://forum.dlang.org/thread/tnwyxmraefedcbypugqp forum.dlang.org
