I read a fortran90 book. It says subroutines and functions
can be overloaded in fortran90. But it seems this is not
true overloading. It can just realize polymorphism.
Say if I inherit a module from a parent module and I want
to overload a subroutine in the parent module but still
keepping the shape of the subroutine, i.e. arguments of the
subroutines are the same. Can this be done in fortran90?
