In principle functions which return a pointer work already (even with procedure
pointers). AFAICS, the only thing missing is using these functions as lvalue,
as in this example:
real, dimension(1:100), target :: array
real, pointer :: p
array(5) = 0.7
print *,storage(5)
p => storage(3)
p = 0.5
print *,p
storage(5) = 0.5 ! Error: 'storage' at (1) is not a variable
contains
function storage(key) result(loc)
integer, intent(in) :: key
real, pointer :: loc
loc => array(key)
end function
end
