Feature request: lang/this-package

[dherman]

I need to be able to document PLT languages with planet module paths. I have a private implementation that looks like this:

(define-syntax (lang/this-package stx)
  (syntax-case stx ()
    [(sp)
     (quasisyntax/loc stx
       (SCHEME (UNSYNTAX (hash-lang)) planet #,(build-planet-id stx #f)))]
    [(sp name)
     (identifier? #'name)
     (quasisyntax/loc stx
       (SCHEME (UNSYNTAX (hash-lang)) planet #,(build-planet-id stx #'name)))]))

But I'm now using your package for defmodule/this-package etc, and it would be good to be able to use your package for everything.
