why? importing tons of unknown stuff into a local namespace is
rather silly, and makes it impossible for the compiler to properly
analyze your code -- which means that you cannot use nested
scoping. the language reference says:
The from form with "*" may only occur in a module scope.
If the wild card form of import -- "import *" -- is used in a
function and the function contains or is a nested block with
free variables, the compiler will raise a SyntaxError.
future versions of Python will most likely issue a SyntaxError also
for "import *" in non-nested functions.

moving the "import *" line to the module scope would have been
enough; functions can refer to module-level variables just fine.
