Hi

I have seen that the php-src uses some flags
like ZEND_EXTENSIONS_HAVE_OP_ARRAY_HANDLER to optimise the code so that the
loop that calls the op array handler is not called if no extension has set
up an op array handler

I wonder why this has not been done for
the statement_handler, fcall_begin_handler and fcall_end_handler. This
could be used to provide an optimised execution when no extension sets up a
handler for these extension points

Interested to know if there is a technical reason for this

Cheers

Carlos
