Original code tries to parse `variable` from `input_item` prior to `expr` from `output_item` that results in issue with following code:
WRITE (99,*) (A(K)*B,K=1,3)
Changing the order of `input_item` and `output_item` in the `io_implied_do_object` is not a correct solution because it allows expressions in the READ statement.
