------- Comment #1 from walter@mail.math.uni-magdeburg.de  2007-11-28 10:27 -------
This bug does not only apply to null as a default parameter, but in every case where a struct OR class should get initialized by another type.

To point out the importance of this issue, I'd like to mention the application of a GMP wrapper library which wraps the GMP types (from the C library) in structs and expression templates. For GMP it is important that one can use these structs like native datatypes:

void foo (mpz arg = 0)
{
  ...
}

one may argue, that you can write "arg = T(0)" (via static opCall), but this
does not work for int, so using mpz like int would not work!

best regards
Matthias Walter
