Thanks for all the replies with interesting suggestions!

For my real-life use case, asDictionary is the most appopriate
choice. It does exactly what I need.
I had discovered newFromKeys:andValues:, which indeed is a good fit
for my small example, but not for my real applications, where the
list of associations comes from another method, so I can't change the
way it is constructed.
What I was most surprised about is newFromPairs:, which works as quoted
although its documentation says something else:
"Answer an instance of me associating (anArray at: i) to (anArray at:
i+1) for each odd i. anArray must have an even number of entries."
