Hi,

Property access with PHP5 is very slow compared to PHP4.  The reason for
this is that property access must be verified *every* time.  This seems
really unnecessary unless we're indirectly accessing properties.

Can/Should this be moved to zend_compile.c for everything that doesn't
rely on indirect reference?

Which accesses are slower,  $obj->prop, $this->prop or both?

It has to be verified each time, because we're typeless, and can't do stuff 
like that in compile time.  It's not related to indirect reference...
