I like the SSI feature. It would fill a nice gap between using plain HTML files and having to go to a more featured template or engine. Some things are simple enough that the SSI concept should be enough, and having Python would be nice.
I do need to give your proposal some more thought before I can properly comment, but it looks interesting so far. One thing I think that *should* be very easy to do in an SSI setting is HTML-escaping. I shouldn't have to do something like 'from cgi import escpe'. Perhaps adding another parameter, like <!--#python esc="h" eval="print '1<2'"--> where esc is a built-in escaping filter: h=html, u=url, x=xml (difference between h and x is how it escapes quote chars). Another question. How are character sets handled? If the output is a Unicode string, how does it get encoded? Should it always asume say UTF-8, or can it determine the actual character encoding for this reponse somehow? Also, my vote is that None should result in no output. -- Deron Meranda
