Returning a splat

[Clunk_Head]

a client that wants to use only functions and the splat is a bit much for them.

In the end, I think this is your real problem.

My hand as it was dealt.

So, I figured it out.
The answer is that I can't.
However, the plt is mutable. So, I can pass the plt as a parameter and apply the legend within the function. Thus eliminating the need to return anything. So my original question was slightly flawed.

Thank you for being my rubber duck on this one.
