Current: assignment_stmt ::= (target_list "=")+ expression_list augmented_assignment_stmt ::= target augop expression_list
New:
assignment_stmt ::= (target_list "=")+ expression_list [where_clause]
augmented_assignment_stmt ::= target augop expression_list [where_clause]
where_clause ::= "where" ":" suite
So the expressions in existing compound statements (for, while, if, elif) would be out of luck. You could conceivably add the 'where' clause to the end of those as well, to give statement local variables that apply to the whole compound statement:
Nick, you're good at formalization, thanks again.
So it seems that people loved the idea of 'where' keyword, may be it's time to think about PEP draft? I appreciate any help (cause my english is not that good =)).
