Subject: How to get parameter names when in set_trace_func callback?

Hi folks,

When my code is executing my trace_function set using set_trace_func how
do I get the parameter names of the function that is being traced? Say
for example I had a function

        def myFunc(firstName, secondName, age)
                do whatever 1
                do whatever 2
                do whatever 3
        end

and my trace function has been called for a line execution event for "do
whatever 2". I can get the filename and line number from the binding.
How do I get the parameter names?

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

Stephen
