strange SyntaxError

[Attila Szabo]

Hi,

I wrote this sample piece of code:
                                                  
def main():
        lambda x: 'ABC%s' % str(x)
        for k in range(2): exec('print %s' % k)

main()

With the lambda line, I get this:
SyntaxError: unqualified exec is not allowed in function 'main'
it contains a nested function with free variables
Without the lambda, it's ok...
     
What's this ?

thanks
