I'll reveal that I'm not Bjarne Stroustrup.  decltype was introduced in 
C++11, which I haven't explored, and I have never written any code that 
resembles your template.  But it appears that an object of type S may 
behave like a function, which in this case would invoke Example.f().  As 
has already been pointed out, one can write "obfuscating code" in any 
language, with little effort.  I strive to write code which is easily 
understandable--and I document it. I don't wish to debate whether I 
could make more of a mess in Python, or not.
