It's news to me that while opCast for all other types is for
explicit
casting, opCast for bool works for implicit casting.
as ag0... mentioned in another thread, opCast is NOT implicitly

In both cases. Like I said, without .ptr, it works, but this

OK, I see now at [1] the following:

The difference lies in the guarantees of const and immutable.
