Jeremy Hylton 81e9502df6 Provisional implementation of PEP 3104. ... Add nonlocal_stmt to Grammar and Nonlocal node to AST. They both parallel the definitions for globals. The symbol table treats variables declared as nonlocal just like variables that are free implicitly. This change is missing the language spec changes, but makes some decisions about what the spec should say via the unittests. The PEP is silent on a number of decisions, so we should review those before claiming that nonlocal is complete. Thomas Wouters made the grammer and ast changes. Jeremy Hylton added the symbol table changes and the tests. Pete Shinners and Neal Norwitz helped review the code.		2007-02-27 06:50:52 +00:00
