-- Hypothesis: global assignment has no inline cache. GET_GLOBAL caches an
-- entry index validated by `globals_version`, but SET_GLOBAL does UTF-8
-- validation, a fresh String allocation, and an IndexMap hash lookup on every
-- write, then re-checks `Builtin::from_name` on the way through.
-- `tally = tally + 1` pays the cached read and the uncached write in the same
-- statement, so the remaining cost here is the write side.
-- Compare against fields/same_obj_write.lua, which measures cached field
-- writes on a table rather than globals.
