I'm not sure about this one, since neither bash nor zsh include regex
matching nor linguistic string conversion. One option that springs to
mind is to change the ASCII case of one of the arguments to match that
of the other (might require changing both, though -- hmm). For example,
in zsh, you would use $NAME:l instead of $NAME. Perhaps a more general
solution is to use regex, such as 'if fgrep -i wurble <<< "$FOO[0-6]" &>
/dev/null; then...'
