Here I have a couple of comments:

> +@vindex $_regex@r{, convenience function}
> +Returns one if the string @var{str} matches the regular expression

I would suggest to say here that 'str' and 'regex' are both C strings,
as you say for $_strlen etc.  Otherwise, the reference to Python could
fool the reader into thinking they should be Python strings.

Btw, what is the technical reason we require Python for these
functions?

Finally, I think it's better to use @findex instead of @vindex
(since these are functions).  Sorry I missed that earlier.

Thanks.
