By "advanced methods" I mean, for instance, python's `.update(other)` method (which allows you to merge two dicts/maps), or `.pop(key)` (which allows you to remove & return a value at the same time). Having such methods on a table which you're still expecting to use as a container sounds like it would allow a attacker to e.g. overwrite your methods if you're processing user-controllable data.
