Ok thanks a lot, how long did it take for you to present that material?

Interesting the part about the learning process, I had a similar
experience, but probably skip this since I only have 30 minutes.

Another thing which I would skip or only explain how it works are
parametrized decorators, in the triple-def form they just look to ugly
to be worth the effort (but at least should be understood).

I think the decorator part is reasonable in testing and prototyping.

Every layor of some decorator just adds more overheads, therefore, 
the syntax sugar of the symbol @ just reminds the programmer the fact.

Acctually writing better wrappers for non-trivial enhancements
to objects or functions should be practiced by professionals.

It is easy to import objects written by others in python. 

It is also user responsible to test and enhance the objects 
from others by decorators, the unittest module, or whatever suitable.


I love to play with functions with a varable representing the time
in writing computer games that emulate  hundreds  to thousands of 
animated obects.

For anyone interested, I already moved the slides on github
(https://github.com/AndreaCrotti/pyconuk2012_slides)
and for example the decorator slides will be generated from this:

https://raw.github.com/AndreaCrotti/pyconuk2012_slides/master/deco_context/deco.rst

Notice the literalinclude with :pyobject: which allows to include any
function or class automatically very nicely from external files ;)
