One issue with both of these solutions is that they will *not* make  
any distinction between the two sets of arguments in the generated  
html/pdf output.  It sounds like you *do* want this distinction to  
get preserved in the generated output.  If that's the case, then I  
think we'll need to define a new field tag.

I'd be fine with any of "Extra Parameters", "Named Parameters", or  
"Optional Parameters"  (There will be some trickiness here, because  
rst will interpret these as eg an "Extra" field with an argument  
"Parameters"  c.f. ":Extra Parameters: ..." to ":param x: ...".  But  
I think that can be handled.)

Using :keywords: is not an option, assuming that you want the two  
sets of parameters to be distinguished in the output -- :keywords:  
already has a meaning in epydoc, and it will not put those parameters  
in a separate section.

I think the standard name should be something like :math:`foo`, but  
that it should be easy enough to expose a hook so you can  
register :m:`foo` as an alias for :math:`foo`.

No, :keywords: is used for keyword arguments.  As of now, I haven't  
added support for adding index terms in rst.  (In epytext, they're  
marked X{thusly}.)  Adding support wouldn't be particularly difficult  
-- presumably the syntax would be something like :indexed:`this`.   
It's just one of many many things I haven't gotten around to.
