Alex: If the node attributes were not mutable, it would be extremely awkward, not to say inefficient, to mutate an already existing AST as returned by ast.parse().
The AST objects in the _ast module aren't what Python works with internally, anyway. When calling ast.parse(), the AST is converted to Python objects (these are defined in Python-ast.c), and compile()ing such an object converts them back to the internal tree representation. This conversion is where recursions would need to be handled. |
