Multibinder requires instances.

[richburdon]

I often use multi-binding where I want to use DI to create instances of the sequence -- hence I can't bind instances directly to the sequence key. My workaround is the utility class below, but it feels like this should be built into the framework (esp. since ListOfProviders is markes @Private)

binder.multibind(Test.SEQ_KEY, ClassProviderList([MyClass])) # Not an instance.

class ClassProviderList(ListOfProviders):
    def __init__(self, classes):
        super(ClassProviderList, self).__init__()
        for cls in classes:
            self.append(ClassProvider(cls))

Sure, that makes sense to me. Send a PR with tests and I'll be happy to merge it.

In my own projects I've been finding myself reaching for this functionality, I opened #197 to add it.

I just ran into the same need. It's quite of a gap that multibind can't work with ClassProvider as normal bind would.
