Funny, Doug Gwyn and I were having a discussion about this just last
weekend on comp.unix.questions.

The problem with the v9 syntax for exportable functions is that it requires
a C library `getenv()' that ignores the definitions and shells that
understand them (for example, this would choke a "regular" System V /bin/sh
started under bash -- either you would have some very strangely-named shell
variables, or the shell would just get all confused).

Bash does have exportable functions; the syntax is "name=() {value}", which
I think is a nice compromise:

kiwi$ echo $BASH_VERSION
1.03.59
kiwi$ type foo
foo is a function
foo () { echo this is foo }
kiwi$ export foo
kiwi$ bash
kiwi$ foo
this is foo
kiwi$
