I am not allowed to do
>>> t = (1, *(2, 3))
Just to be clear, what do you think this means?
What would you expect to happen?
But I am allowed to do
>>> def ts(*t):
... return t
...
>>> ts(1, *(2, 3))
(1, 2, 3)
What do you think is happening here that is different?
I realize I can do
>>> (1,) + (2,3)
(1, 2, 3)
And how does this relate to the use of the asterisk?
Is this what you expect the asterisk version above to do?
What is the rationale behind not having t = (1, *(2, 3))
have the same semantics as the "ts" case above?
That I don't know. The asterisk notation can only be used
for unpacking function arguments, but why it is limited to
that role I don't know...?
