I would be happy with a "local" option. e.g.

def myfunc():
   local spam = ...
   local eggs = ...
   global juice

   breakfast = juice + spam + eggs # raises an exception (undeclared
breakfast)


What I'm *afraid* of is:

def myfunc(MyClass myparam):
   int spam = 6
   str eggs

   # etc

i.e. typed declarations and type checking.  This would annoy the heck
out of me.
