Comment #10 on issue 2125 by asmeurer: Using Integers as python slices.
http://code.google.com/p/sympy/issues/detail?id=2125
I think the whole point of using SymPy Integers instead of Python ints is
that you *can* do something like 1/2 and get a Rational instead of 0 or
0.5. The idea here (if I am not mistaken) is that it would be nice to also
be able use those in the common places where int is used, so that you can
completely replace ints with Integers. Now of course, it is understood
that you will then have to sacrifice integer division (actually, you can
still get it through S(1)//S(2), which is what you should be doing anyway
considering Python 3), and that you will need to use .evalf() if you want
an actual floating point number (in which case, again, a SymPy Real is
going to be nicer than a Python float).
How do others feel about all of this, by the way?
