FWIW there are already three ways for lists/sequences:
[*x, *y]
x + y
x.extend(y) # in-place version
We already have first and third for dicts/mappings, I don't see a big
problem in adding a + for dicts,
also this is not really a new syntax, just implementing couple dunders for
a builtin class.
So I actually like this idea.
