12 * calls the pp_foo() function associated with each op, and expects that
13 * function to return a pointer to the next op to be executed, or null if
14 * it's the end of the sub or program or whatever.
15 *
16 * There is a similar loop in dump.c, Perl_runops_debug(), which does
17 * the same, but also checks for various debug flags each time round the
18 * loop.
