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 [2] called Stylish.

* sasslet: I don't really like too much, but makes clear the connection to
Hamlet and Sass.
* csser/cssar: pronounced "Caesar," might give Shakespeare fans something to
chuckle at.

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