That's … a surprising explanation, especially given that it *looks* like infinite recursion. I would rather that assignment modifier flags (-i, -l, -u, -r} simply be ignored when binding. Then it's a choice between: (a) applying those flags to the variable that it's bound to, or (b) enforcing them when indirectly assigning to a target variable. Since we can already write « declare -i "$reference" », I think (b) would be more useful, and less surprising. Assuming (b) then I would expect an error if «-n» is combined with «-f», «-F» or «-x». Is it worth my while to attempt a patch to implement this? -Martin
