Subject: RFE: Kernel#set_trace_func

Moin!

Would it be possible to let set_trace_func() return the trace func that 
was set before the current one gets stored? This would be very useful 
when you have a temporary trace func that will go away quickly. I'd find 
this particularly useful for letting Binding.of_caller and Tracer 
coexist peacefully, but I'm pretty sure there are a lot more use cases.

Kind regards,
Florian Gross
