This is no different to regular Python code, which has a linear call stack which can have exception handlers at any point on the stack. The exact same tradeoffs apply about which exceptions to raise and which to catch, and at what points. -Andrew. _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
