You might not like global variables, they may not show up much in benchmarks, but people do use them. I suspect a lot of jupyter notebooks have quite a few global variables.


There should not be much of a slowdown for this code when watching `CONST`:

CONST = ... # watched
var = 0
for _ in range(LARGE_NUMBER):
    var += 1
CONST = ... # trigger event.
