Description

If an inner class tries to access a @Lazy property of its outer class it will cause a MissingFieldException unless it either explicitly calls the getter or specifies the outer this.

class Outer
{
    @Lazy lazy   = 'lazy'
    final normal = 'normal'
    final inner  = new Inner()
    
    class Inner
    {
        def f() { normal }
        def g() { Outer.this.lazy }
        def h() { getLazy() }
        def i() { lazy }
    }
}

final outer = new Outer()

assert outer.normal == outer.inner.f()
assert outer.lazy   == outer.inner.g()
assert outer.lazy   == outer.inner.h()
assert outer.lazy   == outer.inner.i()

The expected behavior is that #g, #h and #i are equivalent.
