If nested urls do become part of the core (as I hope), has there been much thought as to what to do with functions? /page/function wouldn't work too well as sub-pages might step on needed functions (or vice-versa).

Maybe there could be an option to specify how we want functions to be delimited? Some examples would be:

site.co.nz/page/sub-page#function
site.co.nz/page/sub-page?function
site.co.nz/page/sub-page.function
site.co.nz/page/sub-page~function

I suggest to introduce a default "index" function to somewhat emulate the standard of delivering an index.html when a directory is called.

A request to root/page/subpage/ would be handled by that default function and simply display the content of subpage (just as root/subpage would do right now), while root/page/subpage/add would execute the specific add function on subpage (root/subpage/add in SS 2.2).

In other words: a slash at the end of the URL simply displays that page, while anything after the last slash is a specific function. This way, pages can be nested as deep as one wants and still have a function, both with pretty and meaningful URLs.

There is a nestedurl branch in subversion which you can use. I haven't used it, so not sure which core version it is based off of.

That's about it really until it gets merged and made official.
