  - don't pass 'handles' down when doing 'has +' to avoid unDWIMmy explosions

  - fix false default values used with non-lazy accessors
  - stop built values that fail isa checks still getting stored in the object
  - stop lazy+weak_ref accessors re-building their value on every call
  - make lazy+weak_ref accessors return undef if built value isn't already
    stored elsewhere (Moose compatibility)
  - stop isa checks being called on every access for lazy attributes
  - bump Devel::GlobalDestruction dependency to fix warning on cleanup
    when run under -c (RT#78617)
