I think this feature has already been implemented for Ruby 2.7. If I am correct, please close this issue. ---------------------------------------- Feature #10118: Double splat for non-symbol keys https://bugs.ruby-lang.org/issues/10118#change-81314 * Author: sawa (Tsuyoshi Sawada) * Status: Feedback * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) * Target version: ---------------------------------------- The double splat operator ** only seems to work with hashes whose keys are symbols. It will not work when a key is a string, for example. This is true for both ways; for construction: def foo **; end foo(:a => 3) #=> nil foo("a" => 3) #=> ArgumentError: wrong number of arguments (1 for 0) and destruction: def bar *; end bar(**{:a => 3}) #=> nil bar(**{"a" => 3}) #=> TypeError: wrong argument type String (expected Symbol) This is confusing. I propose that the double splat syntax should be extended so that it works even when the keys are not symbols. ---Files-------------------------------- 0001-vm.c-allow-to-splat-non-symbol-keys.patch (2.06 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
