foreach should loop over copy of iterable #112

Closed giann closed 9 months ago

giann commented 1 year ago

foreach should operate on a copy of the iterable so that the body of the loop can add/remove element from the iterable.

Ideally it should only do this if the loop body mutates the iterable.
