is something about all these examples (plausibility?) that feels
distinctly different from your proposal.
To me it seems like an unnecessarily complicated syntax that goes
out of its way to look deceptively like something else.
f(a, b, c)
x = a, b, c
f(x)
This imagined refactoring doesn't feel as plausible. A complete beginner
might think that they can do that, but a programmer who knows what
tuples are can reason that it doesn't make sense.
Fun fact -- I gather there was a very early version of Python
in which this refactoring *did* work. But it was quickly changed
because people found it too confusing!
I think what's happening here is that long experience with
other languages has ingrained in us the idea that commas
separate arguments to a function without creating tuples,
so when we see a comma-separated list in the context of a
function call we instinctively think "argument list" and
not "tuple".
But there is no such precedent for the OP's proposal.
