In bash, you cannot return anything from a function other than the
integer error code.

You *also* have access to the function's stdout which may be used as IPC
to send text streams. I suppose you could send elisp objects too, but
the function would need to know how to create and serialize those
objects as... a text stream. And then after capturing that into a
variable, you'd need to pass your text encoded elisp object
serialization to a function that knows how to decode and interpret it.

But the stdout IPC mechanism is not a "return value".
