IIRC you previously had a hack M("Foo") which gives you the foo model,  
maybe we can do something like M("Foo", Load => 1) and M("Foo",  
LoadByCols => foo => 'abc', email => xyz at foo.com') ?  I'd prefer  
polluting the namespace in a more finite and deterministic way, rather  
than having all models generating toplevel package.
so maybe M() for model helper and MC() for collection helper?  I guess  
that would help a lot for plugin writers as well.
