--- Comment #2 from Nathan S. <n8sh.secondary at hotmail.com> ---
Changed from 'bug' to 'enhancement' since the behavior of
ImplicitConversionTargets is correct for its documentation:
```
    If the type is not a built-in value type or a class derived from
    `Object`, the an empty $(REF AliasSeq,std,meta) is returned.
```
