There's no real compatibility here, since typeset isn't part of the Posix
standard.  Most shells, including bash, are concerned primarily with being
able to parse their own output.

There will be a change in the next version of bash that omits the
`function' keyword in posix mode, but that doesn't really help you
if you have to use embedded function definitions now.
