Trying implement empty getter/setter syntax such as:

public $Hours {
   get;
   set;
}

Is there any way to "inject" code into the compile process?

I'm trying via (just some proof of concept code, ignore the buffer overrun =
potential)

                                                char injected_code[1024] =
=3D "";
                                                sprintf((char*)&injected_co=
de, "{ return $this->%s; }", Z_STRVAL(var_name->u.constant));

                                                znode *injected_node =3D em=
alloc(sizeof(znode));
                                                Z_STRVAL(injected_node->u.c=
onstant) =3D (char*)&injected_code;
                                                Z_STRLEN(injected_node->u.c=
onstant) =3D strlen(injected_code);
                                                zend_do_abstract_method(fun=
ction_token, modifiers, injected_node TSRMLS_CC);

However this is causing a segfault, I'm assuming this is because I'm not in=
itializing something of the znode properly.

How can I do this?

Thanks,
