This is, of course, what is shown on the [ruby-lang.org](https://docs.ruby-lang.org/en/2.7.0/syntax/methods_rdoc.html) and [ruby-doc.org](https://ruby-doc.org/core-2.7.0/doc/syntax/methods_rdoc.html) pages on method syntax. This is not true. Example code (2.7) ``` ruby def test(val1, *vals, val2) puts val1, vals, val2 puts "val2: #{val2}" end test(3, 4, 5, 6, 7) # test(3, [4, 5, 6], 7) # this code also works ``` Conclusion: splat/asterisk/array parameters need not be at the end. I will point out that the documentation for Ruby 2.6.5 has the same apparent documentation mistake. The splat parameter need not go at the end for that version either. I did not test other versions. I did not find a related issue here on bugs.ruby-lang.org when searching issues for "method syntax", "method.rdoc" or "array parameter", nor did I find a related issue searching the same terms (checking both open and closed issues) on https://github.com/ruby/ruby/pulls -- https://bugs.ruby-lang.org/ Unsubscribe:
