Partial interface implementation in groovy

interface X {
  void a()
  void b()
}

class XAdapter implements X {
  void a() { println 'default implementation of a' }
  void b() { println 'default implementation of b' }
}

def o = [
  a: { println 'overridden implementation of a' }
] as XAdapter

o.a()
o.b()

will output:

overridden implementation of a
default implementation of b
