This doesn't work because include() is a runtime operation. B.php
doesn't just get inserted into A.php. The behavior is somewhat like a
function call.
While compiling A.php, PHP doesn't know what B is. Therefore the
definition ("binding" to be more precise) of A has to be done at
runtime. And as new A() occurs before class A {} in the code, the
operation fails.
