accessing your scope for template metaprogramming ?

[Sean Cavanaugh]

Is there any way to access the your current scope?  For instance the 
following pseudocode is what I am after more or less:

class Foo
{
  alias byte function(int) BarCompatibleInterface;

  byte Bar(int)
  {
    static assert(is(typeof(localscope) == function));

    static assert(is(std.traits.ReturnType!(localscope) == 
std.traits.ReturnType!(BarCompatibleInterface));

    static assert(is(std.traits.ParameterTypeTuple!(localscope) == 
std.traits.ParameterTypeTuple!(BarCompatibleInterface));

    static assert(is(typeof(localscope.outer) == class));

    static assert(is(typeof(localscope.outer.outer) == module));
  }
}


My desire for this is to help the compiler generate better error 
messages from compilation of string mixins, as they could access the 
function and/or class they are in and give a better error message from 
within a static assert() construct.
