I am always too lazy to look up again where it is that one can do these things. Not that I would ever use such dangerous things myself.
- Magically define variables (so that you don't have to
var('y')) - Magically define functions (so that one doesn't need
boof.annoying_method(), but instead can doannoying_method(boof))
Once it's on here, people can find it more easily and put themselves in more danger.
