I don't know Johan, but I'm pretty sure Håkan didn't talk about performance;
he's more interested in *development* speed... (and I don't think he's been
following 2.4 that closely).
Looking again, the article says:
"Among the news in 2.4 is better performance, especially for new
functions that were added in 2.3."
and then mentions integer/long integer unification and the decimal type as
notable
additions, and continues "and so it continues, with a long list of improved
details".
The article also points to www.python.org/2.4, where the first link is:
http://www.python.org/2.4/highlights.html
which says:
Here are the (subjective) highlights of what's new in Python 2.4.
* Faster
A number of modules that were added in Python 2.3 (such as sets and heapq)
have been recoded in C. In addition, there's been a number of other
speedups
to the interpreter. (See section 8.1, Optimizations, of the "What's New"
document
for more [this lists a couple of thousand tweaks by Raymond, and Armin's
string
concatenation hack]).
* New language features
/.../ unification of integers and long integers /.../ decimal - a new
numeric type
that allows for the accurate representation of floating point numbers /.../
so I don't think you can blame Johan or Håkan... the writer simply read the
python.org material, and picked a couple of things that he found interesting
(decorators and generator expressions may be a big thing for an experienced
pythoneer, but they are probably a bit too obscure for a general audience...)

yes please.

same here. more later.
