I have tried today iPython 0.11 with QtConsole and Sympy 0.7.1.
To run Sympy in iPython with QtConsole, I type $ ipython qtconsole

But how can I use isympy to open iPython QtConsole ? $ isympy
just opens ipython with sympy, without qtconsole.

This is not yet supported. See

ipython qtconsole --profile=sympy should be the equivalent of using

Thanks for the link Jason, there is some good discussion there which it
would be optimal to not have to repeat.
My opinion after reading through that is as follows.

Couple more thoughts on operator overloading.
Let's assume the '+' symbol means 'to add' in the language of choice. It is
very clear that what adding two numbers should do, but what about other
objects:

'+' should add the matrix. we could write a function called 'add_matrix',

I agree with Jason that coercing operators to perform unfamiliar tasks is
probably a poor choice. I disagree however that operators have only a single
