Yes I tried some expriments and even in 2.2 the coercion doesn't seem to happen as expected.
This fails and I can't understand exactly how it differs from what you're
doing in pycanvas.

import sys, string
class Bonkers:
        def __init__(self):
                class F:
                        fontName = 'Times-Roman'
                self._object = F()
        class Action:
                def __init__(self, parent, action):
                        self._parent = parent
                        self._action = action

                def __str__(self):
                        return str(getattr(self._parent._object, self._action))

                def __coerce__(self, other):
                        return coerce(getattr(self._parent._object, self._action), other)

        def __getattr__(self,name):
                return self.Action(self,name)

print sys.version
print iam.fontName,
print string.lower(iam.fontName)
