Hellooooo Jeroen,
This look good to me, but could you say why you replace exmples which use
the "p[x]" variables with examples that do not use this trick? It was
added because it is useful, from time to time, when instead of needing a
'dictionary' of variables you just need 'one' specific variable. With this
trick, you avoid needing to create a dictionary that you wouldn't use much
otherwise.
Aaaaaaaaand as this trick is pretty unknown, some advertisement cannot
hurt `:-)`
