Truly, it would be best to sacrifice the right-hand-side operations. The
rationale for this decision however should be stated on the documentation.
Perhaps someday a compromise of D's operator overloading (or template
instantiation) may be reached which makes these operations possible.

Before closing the variant file however, have a look at #2073.
