GROrderedMultiMap >> #keysDo:

Hi

I have run into an "issue" with GROrderedMultiMap and iteration. The
block passed to it is evaluated for every mapping.

given an GROrderedMultiMap

GROrderedMultiMap new
at: '1' add: 'first';
at: '2' add: 'second';
at: '1' add: 'third';
yourself

#keysDo: will be evaluated with '1', '2' and '1' again. I didn't
expect the last one. Is this the expected behavior?

Cheers
Philippe

Re: GROrderedMultiMap >> #keysDo:

Probably depends on what you want to do. Given that #keysDo: and
#valuesDo: is typically implemented in terms of #keysAndValuesDo: it
kind of makes sense.

Now I don't know if we depend on the current implementation of
#keysDo: somewhere? Why not just use "keys asSet"?

Re: GROrderedMultiMap >> #keysDo:

My inclination is to say that it *doesn't* make sense more than it *does* make sense, but trying to have a multi-value keyed collection implement the dictionary protocol is bound to lead to some confusion...

That would work. What I actually really need is something like
#keysAndAllValuesDo: which evaluates the block one for every unique
key with all the values of this key as a collection.
