(pi/log(real))

I think, there is some syntax misconception.
ask(pi/log(r), Q.real) - meaningless (not good proposition!). Second
argument for ask is an assumption

Comment #3 on issue 1246 by skirpic...@gmail.com: improve solve() to handle
absolute values
http://code.google.com/p/sympy/issues/detail?id=1246
In [2]: x=Symbol('x')
In [3]: solve(abs(x-2),x)
Out[3]: [2]
In [4]: solve(abs(x-2)-1,x)
Out[4]: [1, 3]
Looks ok. Close?

ordering of complex numbers

But
In [89]: Interval(-oo,oo).contains(I)
Out[89]: ⅈ -∞ ∧ ⅈ ∞
and even things like I 2 still work.
