Did you know: Ruby Splat

A lot of times, when I’m not using a particular variable in a given subclass implementation (a dangerous pattern), I give the variable an underscore name to remind future-John:

def thing(_arg1, _arg2)
  # implementation
end

If there are several I’m not using, I throw a splat in, and swallow all of them:

def thing(*_args)
  # implementation
end

BUT, for better or for worse, Ruby splat parameters don’t need names:

def thing(*)
  # implementation
end
