From: Ethan Furman on 29 Jun 2010 13:01 In the glossary section it states: <doc> nested scope The ability to refer to a variable in an enclosing definition. For instance, a function defined inside another function can refer to variables in the outer function. Note that nested scopes work only for reference and not for assignment which will always write to the innermost scope. In contrast, local variables both read and write in the innermost scope. Likewise, global variables read and write to the global namespace. </doc> Doesn't the nonlocal keyword make variables in outer scopes writable? ~Ethan~

For the benefit of people following along at home, it's nice to provide the URL to the ticket. -- Aahz (aahz(a)pythoncraft.com) <*> http://www.pythoncraft.com/ "If you don't know what your program is supposed to do, you'd better not start writing it." --Dijkstra
