Thanks for the goodie. Pardon my limitations, but the above descriptions
leaves me with a few questions:
1) What exactly does it mean to replace the key? I assume that it
assumes the association itself as a mutable object where the key can be
updated (which is not ok), whereas deleting a pair (k,v) and inserting a
new (k',v) is ok?
2) What is the advantage of InvariantKeyAssociation / when should it be
preferred?
Cheers,
Tommy
