Well, A12 did talk about parametric roles, but I glossed over the
first-class roles a bit. I didn't want to scare people with
$foo does $bar
though, of course, there's no reason in principle you shouldn't be able
to do that as a run-time operation. You just can't instantiate a role
object. The murky area in the middle is, of course, how you specify
an initial value aimed at the attributes of a particular role without
creating a "real" object containing just those values. Passing around
lists of pairs is probably good enough for that, as long as you can
keep straight which list of pairs is intended to initialize which
roles.
