Well, not really. The whole idea behind that was perfomance and saved
memory. Currently, I use arrays with two (or three) members a LOT.
I'm not that happy with the fact that the arrays use about twice as
much memory as I'd need to store the two items for themselves. Just a
memory issue.


Maybe a more efficient storage method for arrays would help?
No, it wouldn't. Current overhead for arrays is 2 words (3 in DEBUG),
plus the malloc overhead which is unavoidable anyway. Minimum overhead
would be 1 word + malloc overhead.

Hmm, but maybe tuples which are copied by value? Would be a nice
complement to structs.
