Comment #40 on issue 1047 by fredrik.johansson: Suggested new assumption
system
http://code.google.com/p/sympy/issues/detail?id=1047
Global assumptions would be useful as a complement (I think Maple has
both). Since
var already does some hacks, var('x y z', real=True) could set global
assumptions for
interactive use.
> assert sqrt(x**2).refine(Assume(x, "real")) = abs(x)
In many cases the syntax can be a little simpler, e.g. f.refine(x > 0).
