The thing is the .^does traverses the meta information
to find the *named* concept Point. The FoxPoint in John's
example doesn't have that and thus nominally fails the
Point test. The idea is now to also have
sub foo (Point $p) {...}
to mean
$capture[0].^like(Point)
which does a *structural* analysis.
