That's a good question. I honestly don't use constants all that much, I
like to move such things out to config files. For a constant like math.pi,
it's never been caps, yet people know it's not a great idea to change it.
There are a lot of tools to indicate constantness:

1) provide a property to access an otherwise _plz_dont_touch_variable
2) Use an Enum
3) Use documentation to say: treat this as constant
4) Rely upon consenting adults to not change variables outside of scope.
It's weird to manipulate math.pi because it's in a separate module.

I stopped using all caps a long time ago and it just hasn't created a
problem because manipulating global variables without knowing what they are
is such a bad idea to begin with.
