 From Matt's comments in IRC i might not have been clear enough here:

The point of this is to make URIs for chained actions easier.

Take for example:

/script/foo/rename/newname

Actions for that are:
/script/*/rename/* => /script/script (1) => /script/rename (1)

This then finds out that the script "newname" already exists so provides 
a link to delete that script or to replace the contents with the current:

/script/newname/delete => /script/script (1) => /script/delete (0)
/script/newname/copy_from => /script/script (1) => /script/copy_from (1)

Basically my complaint with uri_for as it stands is that it relies upon 
me knowing the dispatch chain and how many args each chained action 
takes. Yes, I "know" this info, but I shouldn't have to look it 
up/remember it when the dispatcher itself quite happily returns undef 
when I get it wrong...

Any clearer?
