This is done in the backend, which is well beyond parsing and
symbol resolution. It appears that gfortran needs to mangle the
do-variable of the implied-do.

Be careful. I can assure you that it's very tricky code to get right.
Don't forget to do it for FORALL statement constructs as well.

Yep. There are 2 or 3 outstanding bugs associated with implied-do.

integer, parameter :: i = 10
real :: x(10)
x = (/ (i, i=1, 10) /)

There was a problem with this example in g95. I've got it fixed now.


Yep. gfortran gets this wrong.
