Scripting language feature parity document?

I guess this email is more for Doug than anyone else as he did a lot
of work on the guile support.  But when guile was implemented was
there a document on the wiki created describing feature support?.
Sort of like a table with Python and Guile, showing what this supports
and that?

I searched the wiki and came up with nothing really.  If there is not
one around, I can go ahead and create one.  I was thinking of large
features only.  Something like:

                     Python | Guile | Some other future language
===============================================================
Pretty Printers     |  yes  |  yes  | no
Frame Filters       |  yes  |  no   | no
Breakpoint support  |  yes  |  yes  | yes
...
...
(etc)

The last column just for illustration if we have some other future
scripting language.

Cheers

Phil
