@pbackus created dlang/phobos pull request #9039 "Fix Bugzilla 22293:
opCast!bool for Nullable" fixing this issue:

- Fix Bugzilla 22293: opCast!bool for Nullable

  The second opCast overload is necessary to allow built-in implicit
  conversions (e.g., mutable to const) to be performed explicitly via a
  cast expression. Nullable.opEquals depends on this behavior.
