// The following is the current behavior, since both `3+0i` and `3n + 0ni`
// are Complex, but it is unfortunate and hopefully it will be fixed
// with templates:
// The following is the current behavior, since 3 converts to 3+0i
// and 3n converts to 3n+0ni, both of which are technically Complex.
// This will remain the case even with templated Complex, because
// both Complex<bigint> and Complex<NumInt> will refine Complex (for the
// sake of catching new specializations). Not sure whether that will be
// OK or a problem that will have to be dealt with.
