Thanks Gabriel – looks like I really have to spend more time with that
excellent document.

>Whenever I do low-level stuff like this, I'm in one of two modes:
Mode #1: I'm using somebody else's C library and the overhead of
doing so is small.
Mode #2: I need to code my own low-level stuff (for speed, IO access,
whatever).
This seems to be where I am at.
>
In mode 1, I try not to break out a compiler. ctypes is great for
this, and the results are "pure python" to the extent that you can
give pure python to someone else with the same C library, and it will
work. No muss, no fuss, no makefile, no question that ctypes is
awesome stuff.
In mode 2, I have to break out a compiler. I almost never do this
without ALSO breaking out Pyrex. Pyrex is also awesome stuff, and in
Pyrex, you can easily create a (new) Python string for your results
without having to worry about reference counting or any other really
nasty low level interpreter details. You can code a lot of stuff in
pure Pyrex, and you can easily mix and match Pyrex and C.
Pyrex and ctypes are both tools which let me connect to non-Python
code without having to remember to handle Python interpreter internals
correctly. If I can get by with ctypes, I do, but if I actually have
to code in something other than Python to get the job done, I bypass
ctypes and go straight for Pyrex.
Don’t know anything about Pyrex except that it is not in the
standard library on Suse – will try to read up on it. Thanks.

How does it differ from plain old array.array(b,” The quick brown fox”)?

Well after all this discussion it would appear that a 'Python like'
language has appeared => Prothon. http://www.prothon.org/index.html
Very alpha, sort of like Python (if you consider the indenting is what
makes Python unique) and sort of Ruby in its use of prefixes to define
scoping etc (although there is no reference to this trait being borrowed
from Ruby). It also quotes Self as being an influence.

Is there an *easy* way to make an object immutable in
python? Or perhaps I should say "one obvious way to do it"?
Oughtn't there to be one?
I've found a thread on how to do this, which essentially
says something like "redefine __setattr__, __delattr__,
__hash__, __eq__, __setitem__, delitem__ ... and probably
some other stuff too".

I was looking for a function or method that would return the index to the first

be called "find". My first stop was the Sequence Types page of the Library

of the Library Reference's index seemed to confirm that the function did not
exist. A little later I realized it might be called...

You can indeed use ctypes to modify the value of a string - see
<http://tinyurl.com/5hcnwl>. You can use it to crash the OS, too.
My advice - don't.

Not necessarily. You've mentioned two ways.
PS: Umm, a little bit off note: set is a built-in name, I'm a little
confused whether you meant on creating a "set" or setting the push bit
to 1, if the latter case it might be better to use set and clear
instead of passing a second parameter (and also to choose another
name).

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
