Well then, you haven't beed using enouth generator expressions or else, 
that kind of mistake would have bitten you badly by now and you would 
agree with that remark !

Thanks but NO. If that function needs to iterate twice on the 
expression, then it needs to iterate twice and passing it a generator 
will only cause strange bugs.
