On further reflection, I think it's definitely possible to get our current ~80% hit rate up to ~90%. These detailed failure stats will help guide my work on this.

run with this patch applied:Specialization attempts
Note that "add other" and "multiply different types" also correspond more specifically to sequence concatenation and repetition, respectively. Similarly, "remainder" probably contains many examples of old-style string formatting.
I figure it's not worth the clutter of breaking out specific stats for these non-numeric cases yet, since their proportion of the total failures is still pretty low (and the benefit of specialization seems slim).
