4372 :: Can you generate new symbols for procs, templates,etc defined inside templates?

  Say I have the Code Block:

  template test1(a : untyped) : untyped =
    template test2() : untyped =
      echo a
    test2()
  Run

  Whats the best practice to ensure I don't have access to test2 outside of test1? I would normally use a proc but passing untyped data seems to be a problem with them. Here's some code that's closer to what I'm actually trying to do.

  template test1(body : untyped) : NimNode =
    template test2 () : untyped =
      body
    getAst(test2())
  Run

  When I replace template test1 with proc test1 it complains about undeclared identifiers in body.

  I just realized this is a bug and gensym should work on proc, iterator, converter and macros.
