len (list)
I find methods like len to be harder to discover than instance...

Once you learn the "len" method, you know you can apply it to any sequence .
You can write
re.match(r"\w+", "dog")
instead of
pattern = re.compile(r"\w+") pattern.match("dog")
Like You noticed, sometimes it doesn't make sense .

HTTP requests include an Accept-Language header which is set according to your locale preferences on most OS/browser combinations .
I could be way off but I think it's fairly safe to assume that google, is using gears .

I have a container filled with pairs. I want to iterate in it using the STL generic algorithms (in my case it would be inner_product, but consider it as a generic problem). The algorithm I am using expects iterators first and last. Can I provide special...

You'd also need to create your own begin() and end() functions to return your custom iterator .
Std::vector::const_iterator yourself, reimplementing operator* and operator-> to return the first of the pair .

What is the 'correct' way of providing a value in an abstract class from a concrete subclass?
ie, should I do this:

I think the second idiom is better, as it is more manageable... .
Otherwise, either is OK.
It depends; does the base-class need to know about it in the ctor? If so, the override approach may be a bad idea ( virtual doesn't work very well inside the ctor) .

Just pick one, whichever you prefer -- from your comments, I'm guessing RSS... .
But, offering both is probably just a waste of effort .
Most readers support both, so there's no real push for one to take over the other .
I wouldn't say either has or will win.

I dont see the point of doing this as you already have built the path and know what "D" is .
