There is no need to optimise python, it is fast enough.  For me every 
advantage of Python is that I can do what I like with it, when I like 
with it, and I'm not stuck in the dreadful straight jacket of the 
statically typed languages.  If someone wants to make it faster I'm not 
going to complain, but your obsession with speed is going to have me 
dying of laughter if this goes on much longer.

You mean the huge great long list of hard coded function calls.  They 
are directly supported.  So is the loop.  Anything wrong with the Paul 
Rubin response?  And as my earlier link showed you often simply don't 
need a switch statement in an OO language.  Not much point providing 
something, much worse optimising it, if it isn't needed in the first place?

Drivel.  Any establised member of this community, or any other community 
for that matter, will always publish, unless, like the RUE, they've got 
something to hide.  So you're just a chicken.  Where do you buy the 
paint from for the streaks down your back?  Just in case you can't guess 
it is yellow.  I'll state the colour just in case your knowledge of 
colours is the same as your so called knowledge of computing, something 
of which I'm far from persuaded, on the grounds that speed simply is not 
the sole criteria for a language.
