Re: Flag to warning about shape/alignment-change of explicit shape arrays arguments
Code contributions are always welcomed.
IMHO, producing a warning for this specific use case
where the F2018 standard specifically describes sequence
association in 15.5.2.11 seems dubious to me.

It would be reassuring to know that none of the arrays are changing shape, or to see that only the ones so intended do it, especially after doing changes that affect multiple arrays and/or routines.
