I meant checking static expressions at compilation time, as in my example.
This has no cost at run time.
You proposed a run time check that still should be done if requested with a
kind of -fcheck option.
By the way, gfortran is already checking consistency of static arguments to
intrinsic functions, it is that just these one are left unchecked.
