Every time I type `len(some_list)` in Python, I die a little inside.

While I agree to an extent, the reason for this is not entirely bad. The len function is basically a contract that the result you get will be an integer. An object could easily have a `.length` property that is non-integer, like a line/interval for instance. Think of this as a clunky response to a lack of type information in the language proper.
Yeap. I have no hard preference between sin(x) or x.sin, in an OOP context or not, as long as the language is somewhat consistent (e.g., it bothers me that Ruby has some of these functions on the numbers themselves, like 1.23.floor, but others live on Math, like Math.sin(42)).
