Hello everyone,
The following creates three variables ``a``, ``b``, and ``c``::
sage: var('a, b, c')
(a, b, c)
I would expect this to do the same thing::
sage: var(('a', 'b', 'c'))
(('a', 'b', 'c'))
It doesn't, but that's not too big a problem...
This should *definitely* work correctly, but::
sage: var(v for v in ('a', 'b', 'c'))
(<generator, object, <genexpr>, at, 0x56d42d0>)
Yes, that's a tuple! for some reason. Clearly, this is a problem.
The above generator expression should return the same thing as::
sage: tuple(var(v) for v in ('a', 'b', 'c'))
(a, b, c)
