I agree --- in general, it tends to be better to build an unsorted
string list and then sort it.

Once I've done so, what is your advice about getting fast lookups
in the result?  Should I build an auxiliary hashmap as well?  Or
is this an argument for the 'sorted' flag + BUG approach you
already mentioned?

Whatever we do, I agree with your goal of getting rid of
string_list_insert.

Thanks,
Jonathan
