Hash a directory instead of a filename possible?

[eguneys]

Is it possible to append the hash to directory instead of the filename?

So if i reference a directory like

assets.tag('/mydir')

I get a hashed version

/mydir-0923489085

So this would mean if i request /mydir-8w7897234/myscript.js i would get the file /mydir/myscript.js

The reason i am asking is i am trying to integrate this with requirejs, and
i want to set this hashed directory as my baseUrl on requirejs config.

I don't know if this would work, sorry if this is a dumb question.
