Those are a lot more pain than you'd think! This construct already exists in 
C# (static extension classes/methods) and it is causing major headaches there 
- depending on your using statements (equiv. of #include) what looks like a 
simple method call can mean totally different things or not work at all! A 
change in a different section of the class that necessitates an additional 
using directive may cause all kinds of mayhem. It is a nightmare if you have 
to diagnose problems.

In short: the recommendation in the C# world is: "do not use them unless you 
absolutely positively have no other choice." We should take that as a warning.
