[Bug]: UnsupportedSpecializationException with csv.reader

Inizia con gli entry point csv.CSVDialectBuiltins e CSVModuleBuiltins indicati nello stack trace, quindi esegui il reproducer segnalato csv.reader(re.ASCII, int). Traccia la gestione dell’argomento non supportato e aggiungi un test di regressione che dimostri che la chiamata non causa più un crash e produce il comportamento previsto.
