I'm not old on this list but every time there is a proposal, the answer is "what are you trying to solve ?".

Since

|z ={**x,**y} and z.update(y) Exists, I can"t find the answer.

I think the main intentions is to close a gap in the language.

[1,2,3] + [4,5,6]

works for lists and tuples,

{1,2,3} | {4,5,6}

works for sets, but joining two dicts isn't simply

{1:2, 3:4} + {5:6}

but requires either some obscure syntax or a statement instead of a simple expression.

The proposal is to enable the obvious syntax for something that should be obvious.
