Fortran has some aspects of a standard library already, though compared to other languages the shelves are rather bare, let's say. It wasn't until Fortran 2003 that there was a standard way to get command line arguments. Before then different compilers had different ways to do that.
Most users of Fortran are only looking to crunch numbers. That's their application, and for that application Fortran already comes with everything you need, including a large standard library of mathematical functions and operations. I would argue that many users do not have much of a need for anything beyond multidimensional arrays, to be honest. I only know two people who have implemented linked lists in Fortran, for example. That said, it would be nice if Fortran had a good standard library. I would appreciate if Fortran had assertions, for example.
