The purpose of splat is to convert an array into a list of parameters to a
method. Since [] is a method, this happens to work well for including an
array into another array. But that's not its purpose, just a side effect.

There's no real concept of converting a hash into a list of parameters to
a function, so there's no splat notation for it.

If you want to combine hashes, use the merge method

{:c=>3}.merge(h) #=> {:a=>1, :b=>2, :c=>3}
