Subscripting array-valued expressions as if they were arrays

[Beliavsky]

In Julia and some another languages, you can subscript array expressions as if they were arrays. So in Julia

    (1:3).^4  = [1, 16, 81]
    ((1:3).^4)[2]  = 16

Would that be hard to implement in Fortran? It would make some code shorter by removing the need to instead
(1) declare an array
(2) set the array to an expression
(3) subscript the array

Given the standard allows

   associate ( x => [ 1, 2, 3 ]**4 )
      print *, x(2) 
   end associate
end

that takes care of about half the "needs", you may not get much response.

Steve Kargl explains some of the issues with subscripting expressions here. I will be closing this issue.

We should document the associate thing at https://fortran-lang.org/learn/ as a workaround.
