Subject: [ruby-core:64251] [ruby-trunk - Feature #10118] [Open] Double splat	for non-symbol keys

Issue #10118 has been reported by Tsuyoshi Sawada.

Feature #10118: Double splat for non-symbol keys
https://bugs.ruby-lang.org/issues/10118

----------------------------------------
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.
