Most of the time we get a
[".class-name" {styling}]
tuple, but we may also get aCSSAtValue
, or possibly any number of special Garden things. So instead ofspecial-casing these patterns, we walk whatever we get, replacing the classname
of the current token with
:&
. In a second pass we unpack the pattern[:& styling]
, this isn't necessary, but helps create more compact CSS.
