Yeah, that's true.  I was thinking that require_role could accept an
arrayref of roles instead of a straightforward role, if desired, so you
could also say e.g.:

    get '/foo' => requires_role ['Foo','Bar'] => sub { ... };

(requires_roles could be added as an alias, so code could read better.)

I imagine the common requirement will be to say "any of these roles",
not "all of these roles".  I was considering whether requires_role
should be for "must have this role" or "must have all of these roles",
and e.g. a new requires_any_role keyword would be added to ensure a
user had all the specified roles; I'm not sure how valuable that would
be, though.
