While there's no guarantee of short-circuiting in the Fortran standard (so
don't rely on it to avoid looking off the end of an array inside the
conditional), it's not forbidden by the standard either and every compiler
we support implements it (I checked some time ago, even old versions like
gfortran 4.1.2). So the performance implications are more of a pedagogical
concern than a real one.
