Good point. Some languages (Standard ML for one, as I recall) don't
even allow conversion on assignment. Fortran would be safer if it
allowed no implicit type conversions.
I'd be interested to just know how the various compilers behave in
this respect now. I used to have several but now only two and one
reports and error and one just a warning. For MPI interfaces, I think
the answer is just to use default kinds and allow C wrappers to untie
the -i4/-i8 mess.
