Its current meaning lends itself to the extremely convenient

Dictionary withAll: {#a -> 1. #b -> 2}.

as class>>withAll: is defined as something like "self new addAll: arg".

I prefer the semantics of addAll: to definitely be "arg do: [:each|self
add: each]", but this would change or be special-cased if you could
addAll: aDictionary in the manner parasti speaks of.

Perhaps a new method, like addAllAssociations:, which would be
semantically equivalent to "arg associationsDo: [:assoc|self at: assoc
key put: assoc value]", would be more appropriate?
