Comment #3 on issue 2406 by [email protected]: improve Tuple constructor
http://code.google.com/p/sympy/issues/detail?id=2406
I implemented the sympification of the args in
https://github.com/renatocoutinho/sympy/commit/a7db82ff88baab2b21768d5cfa652eb69b998702
I had to do it in Tuple.__new__, because messing with Basic.__new__ was
making sympy unimportable. I even tried to sympify args inside a try: block
and it didn't work either.
I'm not sure about from_iter -- you suggest to include it in Basic instead
of Tuple, and I don't understand why (are there other containers derived
from Basic?). Also, numpy uses "fromiter" without _, perhaps this would
feel better for people used to it.
