This routine is a one-liner and doesn't really need to be function and
should be rather implemented as a macro.

V1->V2:
- The previous implementation was fixing a compilation error that
occurred only with old compilers (from 2015) due to a bug in the
compiler itself.
- Dave suggested to rather implement this as a macro which made more
sense.
