Subject: How can I get the return value from a Ruby function, but inside the set_trace_func callback?

Hi folks,

When my code is executing my trace_function set using set_trace_func how
do I get the return value for a ruby return event? Say for example I had
a function

        def myFunc(arg1, arg2)
                result = arg1 * arg2
        end

and my trace function has been called for the return event for the
myFunc() function. The function always returns the last data item
evaluated, which in this case is result. Can I determine this value from
inside the trace function? If I can how do I do so?

I've spent all this afternoon trying to do this (and the other problem
in my other question), examining the Ruby source, but can't work it out.
Hope someone can help me, or tell me it can't be done :-(

Stephen
