| Implicit conversion may be one way to go. Another way could be to use type

I think Hervé is quite fluent in template metaprogramming and its
basics (after all, he significantly contributed to CGAL :-).
IMHO, the issue is more about the usefulness of the implicit type
conversion in the scope of interval arithmetic, compared to the
interface complication.
