Then, you are then suggesting ${Z[0]} instead $Z for the first element
of the Z array, for the same logic.

I'd rather have $Z as a shorthand notation of ${Z[0]} for the fewer
keystrokes. Bash is for command line interaction, every keystroke
counts. If you want verbosity, you can use java. It is notorious in
this aspect so that people literally have to use an IDE to deal with
the bloated code in java.
