Why does the compiler(parser) not give an error or warning if an abstract method(function) is not implemented by a subclass

Expected and Actual Behavior

When the class B in Zephir (which inherits from an abstract class A)vhas to implement at least one abstract methods, gives now at runtime the error:

"Cannot instantiate abstract class B"

What I expect that during the build the compiler(parser) will notice, or even gives an error which tells me that 1 - Class B must be abstract or 2 - Class B must implement the abstract method

Is this a 'bug'/missing feature, or is this a config setting which a have missed?
