I have a struct with a mixin(bitfields) containing many small bitfields. I also have a class member in the struct.

And because I want the class member to compare by using `is` I need to define

    bool opEquals(const scope typeof(this) that) const @safe pure nothrow @nogc
    {
        return (this.data == that.data &&
                this.context is that.context &&

                // these are all bitfields members
                // TODO can we do this comparison in one go?
                this.lang == that.lang &&
                this.pot == that.pot &&
                this.manner == that.manner &&
                this.senseNr == that.senseNr &&
                this.hasUniquePot == that.hasUniquePot &&
                this.isHashed == that.isHashed);
    }

Is there a way to make the bitfields-comparsion in opEquals run faster by somehow checking for its size in words (n) and casting it to size_t[n] which can be compared very fast.
