ksh93+, (ksh was the shell the OP specified), also supports negative indexes, to indicate elements from right to left (probably after a certain revision level).
zsh also does this, but the first index of arrays is 1, rather than 0..
bash requires version 4.3 or higher

SHCOMP(1) User Environment Utilities SHCOMP(1)
NAME
shcomp - compile a ksh93 shell script
SYNOPSIS
shcomp [ options ] [infile] [outfile]]
ORIGIN OF THIS MAN PAGE
This man page was written by Christophe Martin <Schplurtz@free.fr> for the Debian GNU/Linux system. It is based on "shcomp --man" output.
DESCRIPTION
Unless -D is specified, shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh93 can read and execute
with the same effect as the original script.
Since aliases are processed as the script is read, alias definitions whose value requires variable expansion will not work correctly.
If -D is specified, all double quoted strings that are preceded by $ are output. These are the messages that need to be translated to
locale specific versions for internationalization.
If outfile is omitted, then the results will be written to standard output. If infile is also omitted, the shell script will be read from
standard input.
OPTIONS
-D, --dictionary
Generate a list of strings that need to be placed in a message catalog for internationalization.
-n, --noexec
Displays warning messages for obsolete or non-conforming constructs.
-v, --verbose
Displays input from infile onto standard error as it reads it.
--man Displays this man page on standard error and exits.
--help Shows a short help message and exits.
EXIT STATUS
0 Successful completion.
>0 An error occurred.
DEBIAN WARNING
On a Debian GNU/Linux system, more than one package may provide ksh. the output of shcomp can only be used by ksh93. Any other ksh will be
unable to run the compiled script.
EXAMPLE
( echo '#! /bin/ksh93' ; shcomp myscript ) > myscript.bin &&
chmod 755 myscript.bin
./myscript.bin
