For that matter, with bash, we should use:
$ /bin/sh -c 'set +o posix; a-b() { echo hi; }; set -o posix; a-b'
hi
so that the rest of the script avoids any other bash extensions
incompatible with POSIX (does it strike you odd that bash lets you invoke
a function with an incompatible name, even though it won't let you define
it?).
