Humm, you seem to have misunderstood (& that could be one reason in itself). In my example foreach() iterates over the original $arr array (contrary to what you say) - and so may deeply nested fns in the called do_something() method, making global + foreach construct unuseable/"unstable" in non-trivial cases.
