Triggering such a "method" would lead to a segfault due to a stack overflow.
Of course one can still trigger this by e.g. having two operations
foo
andbar
, and installingfoo
as method forbar
and vice-versa. But that is farless likely to happen by accident. Also, it seems better to fix at least some
instances of this issue than to give up because we can't fix it completely.
(This used to be PR #4349 but I accidentally deleted the underlying branch, it seems, so I had to reopen it in a fresh PR)
