Treat this similar to keyword splatting nil, using goto ignore. However, keep previous behavior if the method accepts a keyword splat, to avoid double hash allocation. This also can avoid an array allocation when calling a method that doesn't have any splat parameters but supports literal keyword parameters, because ignore_keyword_hash_p was not ignoring the keyword hash in that case. This change doesn't remove the empty ruby2_keywords hash from the array, which caused an assertion failure if the method being called accepted keywords in some cases. Modify the assertion to handle this case. An alternative approach would add a flag to the args struct so the args_argc calculation could handle this case and report the correct argc, but such an approach would likely be slower.
What is Ruby?
Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.
Features of Ruby
- Simple Syntax
- Normal Object-oriented Features (e.g. class, method calls)
- Advanced Object-oriented Features (e.g. mix-in, singleton-method)
- Operator Overloading
- Exception Handling
- Iterators and Closures
- Garbage Collection
- Dynamic Loading of Object Files (on some architectures)
- Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://docs.ruby-lang.org/en/master/maintainers_md.html#label-Platform+Maintainers
