  Target Milestone: ---

With an effectively empty (i=m,n and m>n) array constructor :


$ cat z1.f90
program p
   integer i
   print *, [(f(i), i=2,1)]
contains
   function f(n)
      integer :: n
      character(:), allocatable :: f
      character(3) :: c = 'abc'
      f = c(n:n)
   end
end


$ gfortran -g -O0 -Wall -fcheck=all -fno-frontend-optimize z1.f90
z1.f90:3:25:

    print *, [(f(i), i=2,1)]
                         1
Warning: DO loop at (1) will be executed zero times [-Wzerotrip]
