A solution offered to the problem of change propagation in lazy Moose attributes was to use lazy_build => 1 in the lazy attribute and then, in the attributes referenced by the builder: 

has 'attr1' => (
    ...
    trigger => \&clear_attr2, 
);

However, this requires maintaining back-references in the source code that could have been created along with the memoized value at build time. Is there a MooseX that does this automatically?
