mixins should make it possible to write a plain old Haskell function to
output multiple border-radius statements. I might even include such a mixin
in the main package.
Regarding concatenating stylesheets: I believe that would have to be handled
at the level *above* Stylish; Yesod, for example, automatically concatenates
all style statements added via the addStyle function.
There's also a Firefox and Thunderbird extension  called Stylish.

As it stands, I'm leaning fairly strongly towards including Stylish in the
