35742 1c4d192f1568 Merge ast-branch to head Jeremy Hylton <jeremy@alum.mit.edu> parents: 32121 diff changeset	326 explicit global is declared with the global statement. An implicit

1c4d192f1568 Merge ast-branch to head Jeremy Hylton <jeremy@alum.mit.edu> parents: 32121 diff changeset	328 in an enclosing function scope. The implicit global is either a global
1c4d192f1568 Merge ast-branch to head Jeremy Hylton <jeremy@alum.mit.edu> parents: 32121 diff changeset	329 or a builtin. Python's module and class blocks use the xxx_NAME opcodes
1c4d192f1568 Merge ast-branch to head Jeremy Hylton <jeremy@alum.mit.edu> parents: 32121 diff changeset	330 to handle these names to implement slightly odd semantics. In such a
