Yes. Back when I followed c.l.f, several experts did advise people to never use functions unless they were pure (or more or less effectively so, if they didn't fulfill the standard requirements for purity). Considering that at least some of those same experts were also part of the Fortran standards committee, I just find it very strange that, to the best of my knowledge, no effort to fix this has been done.
That is a bit distorted, at least from what I remember. The advice was rather "If you use functions with side effects, you may have problems". Something quite different.
Very strange indeed. If someone tells me "don't use functions in Fortran", then what I hear is "don't use Fortran, it's broken".
Well, nobody did, to the best of my knowledge (and I followed the same discussions).
