C api and exception handling

[lallous]

Hello,

Is there is a way, using the Python C api, to install an exception handler 
that:
- will be triggered when an exception occurs
- analyze the reason of the exception
- correct the situation and try again (something like exception handling on 
windows where the exception handler can retrieve the registers 
context->faulting instruction->fix situation if needed->restart execution 
from the same point)

Since I will be asked: "what are you trying to achieve?", this is what I 
want:

func_call("hello") <- no exceptions, good code: function is defined and 
called properly
SomeUndefinedFunction("x", "y") <- undefined function call will trigger an 
exception. I want my python/C exception handler to inspect the reason of the 
exception, if it was a call to an undefined function call then redirect the 
execution to a certain method, say: ExecuteByName("SomeUndefinedFunction", 
"x", "y")

I know if I create a small class with getattr hooked, what I want can be 
achieved.

But can it be done otherwise (without using a class and instead relying on 
exception handlers and correcting the exception)?

Elias
