It's controversial at least (IMO) because it violates the one entry,
one exit theory, and can also make it harder to maintain a function
that may need to perform cleanup of local resources before exit.

Whether or not a given person agrees with those (or other) issues is
open to debate, thus the controversy.

Unless your "i don't think so" was just agreeing that it's
controversial :-)
