Bug description:Overriding and derived classes
Description:
------------
https://github.com/php/php-langspec/blob/master/spec/14-classes.md#general
"Methods and properties from a base class can be overridden in a derived
class by redeclaring them with the same signature defined in the base
class." This is not accurate. When a derived class overrides a method,
if there is no abstract decl (either abstract decl in an abstract parent
or a decl in an implemented interface) in the inheritance hierarchy then
whatever signature you want can be used for the derived method. If there
is an abstract decl in the inheritance hierarchy, then the derived
method's signature must match the signature of the abstract decl.
