How to overrride a function defined inside a function

Hi all:

In https://issues.roundup-tracker.org/issue2551105 we have the need
to override the options passed to the various markdown backends.

Currently the options are defined in roundup/cgi/templating.py using a
scheme like:

  def _import_markdown():
     do imports etc.

     class SomeClass(Markdown.Class):
        override some method defs

     ...

     def _options(config):
            options = { 'fenced-code-blocks' : {}, 'nofollow': None }
	    # in some cases options is something like:
	    # options =  [SafeHtml(), 'fenced_code']
            if config['MARKDOWN_BREAK_ON_NEWLINE']:
                options['break-on-newline'] = True
            return options

     markdown = lambda s, c: markdown_from_parent(s, extensions=_options(c))

     return markdown

Is there a way to redefine _options inside of_import_markdown (it
would be done using interfaces.py) or should I restructure this to
have a MarkdownOptions class with _options defined within it and
change import markdown to end with:


     markdown = lambda s, c: markdown_from_parent(s,
                       extensions=MarkdownOptions._options(c))
     return markdown

Thoughts?
