Try this:
role(:web) { ["domain", {:primary => true}] }
In other words, the block should return an array corresponding to the
arguments you would normally have passed to role(). The first _n_
elements of the array are domain names to assign to the given role,
and the last option may be a hash containing the properties to set on
those servers (e.g., :primary => true, and so forth).
