Any objections to modifying zend_lookup_class() to support fully
qualified class names? Meaning, if it's passed 'A::B' it will lookup
class B in namespace A? This change would take a care of several places
in the code where class name can be passed.

+1, because your patch is likely to fix the issue #21094.

I'm not sure if it's a good idea to change it or if we'd want a new 
function because zend_lookup_class() is used in the core executor and this 
would just slow it down. Can you give me an example of where you'd want 
this to work?

Could you point out which places are these?

zend_builtin_functions.c:

    575: if (zend_lookup_class(Z_STRVAL_PP(arg), Z_STRLEN_PP(arg), &pce TSRMLS_CC) == SUCCESS) {
	673: if (zend_lookup_class(lcname, Z_STRLEN_PP(class_name), &pce TSRMLS_CC) == FAILURE) {
	740: if (zend_lookup_class(Z_STRVAL_PP(class), Z_STRLEN_PP(class), &pce TSRMLS_CC) == SUCCESS) {

Basically, any functions that take the name of a class and need to
obtain the corresponding class entry, should also be able to take the
namespace::class syntax. zend_lookup_class() seems like the best place
to accomplish it. Any other suggestions?
