Bash has an option that tells it to (attempt to) restrict itself to

I haven't used this option myself, and I don't know just how closely it
actually conforms to POSIX.
 
I'm less familiar with ksh and zsh, but they probably have similar
options.  At least the "MirBSD Korn shell" has "set -o posix".

The branch ksh93u+m has it...

$ set -o | grep -i posix
posix                    off

But original ksh93u+ doesn't show such an option.
