Thomas,
Could you add BUILD_*_UNPACK opcodes documentation to
Doc/library/dis.rst? It would also help if you modify CALL_FUNCTION_*
opcodes' documentation to explain how they will interact with unpacking
opcodes.
Do I understand correctly that non-starred arguments are packed into
intermediate tuples/sets in the presence of starred arguments so that
{a,b,*c,d,e} is equivalent to {*{a,b},*c,*{d,e}}? This should not be a
problem for tuples, but with sets, it means that {a,b,c} may behave
subtly differently from {a,*(b,c)}.
