I wasn't aware of this, but apparently the and and or keywords aren't operators. They don't appear in the list of python operators . Just out of sheer curiosity, why is this? And if they aren't operators, what exactly are they?

They're keywords , because they're reserved identifiers, not special tokens of symbols .
They're classifying them as keywords earlier in the document.

Sooo...it's only sort of programming related, but I figure it's election day, right? Is there a single good reason why they aren't, not necessarily open source in that anyone can contribute, but open source in that anyone could inspect the source?

If you're using an embedded asset, the width / height properties are available immediately... .
Most probably, the swf is not at the right path or is not getting copied to an assets folder in the debug-build/release-build directory .
Check your asset path.

Can anyone think of a way (perhaps using a PowerShell script or similar) where I can look for *.cs files that are on disk in the folder structure, but aren't included in a project file?
This has come about gradually over time with merging in Subversion...

"Show all files" button at the top of Solution Explorer, then manually inspect? .
Works, but is inefficient.
All your .cs files will be mentioned in the project file, right? Scrape the XML, list the files and then do a search on the whole system .

If I'm using Objective-C, here's how I declare an initialize an int:
int a = 1;
vs an object:
myObj *a = [[myObj alloc] init];
So this is a pointer to an object as denoted by the '*'. My question is, why aren't objects of type id declared this way? I....

Because id is defined as:
typedef struct objc_object....
You can always treat it as typedef <some-mysterious-root-type>* id if you want .
Identifier isn't the object itself.
Identifier, like pointer, identifies the object.
Because id means identifier.

I guess this have been answered before, but I just couldn't find the answer here or on Google, but I think that it is because I couldn't type the right question...

Because initialisation takes time.
Why it is done like that in C, is another question, but I think that the zero overhead principle was involved somehow in this design decision .
For historical reasons, mainly because this is how it is done in C .
