I agree, I just used print as an example of reading the value, not
setting it.

It doesn't work if you try to do guess_what=foobar, meaning
array[4]=foobar.

The manual says "Recognize the same escape sequences as the print
builtin in string arguments to subsequent flags." So there should be a
relation.
