I understand that the standard Python distribution is considered
the C-Python. Howerver, the current C-Python is really a combination
of C and Python implementation. There are about 2000 Python files
included in the Windows version of Python distribution. I'm not sure
how much of the C-Python is implemented in C but I think the more
modules implemented in C, the better performance and lower memory
footprint it will get.
I wonder if it's possible to have a Python that's completely (or at
least for the most part) implemented in C, just like PHP - I think
this is where PHP gets its performance advantage. Or maybe I'm wrong
because the core modules that matter are already in C and those Python
files are really a think wrapper. Anyhow, if would be ideal if Python
has performance similar to Java, with both being interpreted languages.

I'm not quite sure I understand that criticism. How is that different
from things which are not properties?
foo.baz = 2 # oops, I meant bar
will succeed regardless of whether foo.bar is an attribute or a property.
Unless it's a new style class with __slots__

Naw, I'll skip the rant this time. ;-)

Personally I find properties atrocious and unsafe.
What a strange observation from someone wanting to introduce defmacros
and customizable syntax in Python....
One cannot
distinguish between a function call and binding an attribute in a
statement like:
FWIW, "binding an attribute" will *alway* require some function call...
Properties - or any other computed attributes - are just hooks into the
default __setattr__ implementation so you can customize it.
foo.bar = 2 # Does this call a function or bind an attribute?
From the client code POV, it binds an attribute - whatever the
implementation is.
From the implementation POV, it will always call a couple functions.
What's you point, exactly ?
# Is this foo.setBar(2) or setattr(foo,'ba r',2)?
Why do you care ? Ever heard about the concept of "encapsulat ion" ?
Even worse: if we make a typo, the error will not be detected as the
syntax is still valid.
So what ? This has nothing to do with properties.
Properties and dynamic binding do not mix.

However, the documentation avialable at PHP.NET suggests that it

and accurate in any sense? (There's lot of user clarifications
which show that it isn't complete).

Hi,
I use view to join difference table together for some function. However,
when the "real" table fields changed (e.g. add/delete/change field). The
view table still use the "old fields".
Therefore everytimes when I change the real table, I also needed open the
view table and save it by SQL enterprise manager manually for update the
view table field.

I want to know how functional indexes are used "in the real world". Here
are the common uses:
* non-unique index on the first parts of a longish text field
(SUBSTRING(field)) to save disk space, while still allowing faster
searches than a sequential scan.
* indexing on LOWER(field)/UPPER(field) to allow case-insensitive
searches or case-insensitive unique constraint.

Hi everyone
I need to move on a step in my PHP...
I know what classes are, both in PHP4 and 5 and I'm aware of "patterns"
existing, but what I'm looking for are some real world projects eg. Open
Source that people consider to use classes and patterns correctly.
I lack a senior person to lead me in this so I feel I'm losing out on
only using bare PHP class features and not really knowing how to design

"real" XHTML served as content (MIME) type application/xhtml+xml will display in MSIE 6.0 release 2900 and 7.0 but they will not render xml content. However, MSIE 6.0 release 2800 and earlier displays a download screen -- selecting OPEN presents a plain, text only, rendered page -- sans style sheet.

The difference between compile & runtime. CreateInstance works at
runtime, you can pass ANY string to it (even an incorrect one like
"123123123123") and it will compile
Only at runtime you will get the error.
And honestly, you HAVE to know something about your Class. otherwise,
how do you know which method to call?
