Wait! second that. We would like to

###############
def bar():
      raise

def b5():
     try:
         raise A
     except:
         bar ()
#################

So, restricting raise into except clauses only, is not good.
Change the proposal to:

 >      or UnhandledException.

here is another confusing case:

###################
import sys

class A:
  pass

class B:
  pass

def foo ():
     try:
	raise B
     except:
	pass
     raise


def b1():
  try:
    raise A
  except:
    foo()

try:
     b1 ()
except:
     print sys.exc_info()[0]
##################

This reports that __main__.B is raised but wouldn't it be better
to raise an 'A' since this is the currently handled exception?
