That's the only possibility that I can think of.
There is a "return" builtin in bash, but it cannot have an argument:
it just exits the function.

Do you know the Advanced Bash Scripting Guide?

Lots of -- the title is not unclear about it -- advanced scripting tips 
and tricks. You may really certainly like it.


ps: don't know if you already got personal responses, but on techtalk
(which among other things discusses "everything shells") you may have 
better chances to get an answer.
