  1. store_list creates tuples rather than lists
  2. It has an unused merge parameter (from when we used to use store_list to flatten lists).
  3. It requires more allocations than are strictly necessary because it takes a Vec and then copies it to change its shape.


Rename to store_tuple, remove the merge parameter, and change the signature to taking a &[Value], which allows for use of arrays on the stack, as well as direct usage of Vec<Value>, which we have in most (all?) cases.


Fewer allocations, simpler API.
