As someone who sometimes steps out of the comfort of writing scheme, I agree with you. I spent a lot more time writing python than I did ruby, but with ruby I can just jump right in and things work like I expect them to. With python there is always small semantic things that moves the whole experience into slightly uncomfortable territory.

But whatever floats people's boats. If I had to do numeric computation I would chose python as well, but personally I would become a grumpy fart that would complain way too much
