Issue #19829 has been updated by matz (Yukihiro Matsumoto). Status changed from Open to Closed I see no benefit from the proposed change, other than you cannot tell the method takes any keyword argument or not at all from the error message. In that case, I advise reading the document. Matz. ---------------------------------------- Bug #19829: Enumerator.product called with keyword arguments raises exception with not precise message https://bugs.ruby-lang.org/issues/19829#change-104267 * Author: andrykonchin (Andrew Konchin) * Status: Closed * Priority: Normal * ruby -v: 3.2.1 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- The `Enumerator.product` method, added in Ruby 3.2, when it's called with keyword arguments (but it expects only a list of enums) raises `unknown keyword: ... (ArgumentError)` exception: ```ruby Enumerator.product([], a: 1) # (irb):1:in `product': unknown keyword: :a (ArgumentError) ``` But AFAIK `unknown keyword` is used when a method expects keyword arguments and some not supported keyword arguments were passed. So I would expect raising exception with `no keywords accepted (ArgumentError)` message instead that states clearly that no keywords should be passed. -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
