[IronPython] Callstack inspection

[Gary Stephenson]

I would like to adapt the following code to IronPython, but there appears to 
be no inspect module available.

Any clues on how I might proceed?

many tias,

import inspect

class _gsDynamicVars( object ):

    def __init__( self ):
        self._publics = {}

    def setPublic( self, nm, x = None ):
        self._publics[nm] = x

    def __getattribute__( self, nm ):
        for f in inspect.stack():
            if f[0].f_locals.has_key( '_privates' ):

                    return f[0].f_locals['_privates'][nm]
        return self._publics.get(nm)

    def __setattr__( self, nm, x = None ):
        for f in inspect.stack():
