Consider:

zsh% setopt | grep set
nounset             off
zsh% echo ${thisisnotavariable}

zsh% echo ${thisisnotavariable[1]}
zsh: closing brace expected
zsh% 

Why is it a *syntax* error to subscript a variable that's not set, when
it is not a syntax error to refer to the string value of such a variable?
