Unfortunately no, because I don't need it only for printing, but for
referencing as well. I have an array and I'd like to access the
elements by more meaningful names, so I tried to do

% alias -g guess_what='array[1]', etc.

Your suggestion doesn't work however when an assignment has to be made
to guess_what.

I did but didn't see this possibility. In fact I still don't see...
What's the relation between recognizing the same escape sequences as
print and making a substitution? I'd be grateful for an explanation.
