[Zope3-dev] reasonable syntax for multi-adaptation

[Brandon Craig Rhodes]

The current syntax for multi-adaptation makes the interface look like
an object of the adaptation, rather than the actor in the operation.
Instead, multi-adaption should look like this:

  IFoo(multi=(obj1, obj2))

or:

  IFoo(multi=(obj1, obj2), name='site_foo')

The first draft of such an implementation could simply intercept a
"multi" keyword passed to InterfaceBasePy.__call__(), and hand control
over to the traditional getMultiAdapter.  The old getMultiAdapter call
should always remain available, but code will become much easier to
read as the new syntax is adopted and single- and multi-adaptation
become visually congruent.

I'll be happy to develop a patch and test cases.
