I wouldn't say terrible. Unclear perhaps, but functional. Try this exercise:

false, true = 0, 1 # or use an old Python
if true + true:
    print("true OR true is true")

As long as you accept that any non-zero value is true, and as long as
'and' and 'or' are the only operations you use (you can add 'not' as
long as it's defined the same way: "false if x else true"), addition
for or works fine.
