Checking for unbound_vars_is_error can be done earliest if you worry
about additional runtime weight. It makes the code for disabled `set
-u` instances optimal b

var[@] refers to all the elements and not the variable itself so I'll
find that painful to use. The solution to check want_attributes is
simpler.

Obvious workaround would be to disable `set -u` temporarily or assign
a temporary array value but that shouldn't need to be done.
I'll consider it, but I'm not eager to carve o
Changing "c == '@'" to "c == '@' && !want_attributes" in line 10145 of
