New issue 2403 by [email protected]: simplify could accept more symbol
containers
http://code.google.com/p/sympy/issues/detail?id=2403
Only tuple and list are being allowed right now but we now work with sets,
too, and Tuple. Perhaps we need a list_like utility function to
standardize this with an option to allow dictionaries:
def list_like(i, dict_ok=True):
if type(i) is dict and dict_ok:
return True
return hasattr(i, '__iter__') or hasattr('__getitem__')
Perhaps there could be an option to exclude iterators.
For now I'm just allowing anything with the iter or getitem attr.
