Run-time execution time is not everything, otherwise the
whole world would still be using Assembler for all
programming.
Hacks often adversely affect maintainability of any given
system. For example, the computed goto hack relies on
separate definitions of all opcodes. Failing to keep this
list up to date can result in subtle, hard to diagnose
failures which is undesirable for a stable system (PHP 4).
