Appropriate datatype for holding percent values?
...r potentially even into the negatives).
Treat value 1 as 100%, 0.5 as 50%, etc. This will allow any math operations to function as expected (i.e. as opposed to using value 100 as 100%).
Amend precision and scale as required (these are the two values in brackets columnName decimal(precision, scale)....
Why doesn't Objective-C support private methods?
...why alter the semantics of the language, as well as the compiler, runtime, etc., to add a feature that's already emulated in an acceptable way? As noted in other answers, the message-passing semantics -- and their reliance on runtime reflection -- would make handling "private" messages non-trivial.

A partial application will take the function and parameter(s) and return a function that requires one or more less parameters, and as the previous two examples show is implemented directly in the standard F# function d...
Why does CSS not support negative padding?

Are there any O(1/n) algorithms?
...he numbers, minimum of time that sleep can wait, time to process arguments etc.): this limit would then be a constant lower bound so in fact the above function still has runtime O(1).
But there are in fact real-world algorithms where the runtime can decrease (at least partially) when the input size...
Calling a class function inside of __init__
...results_from_parse
By the way, if you have variables named stat1, stat2, etc., the situation is begging for a tuple:
stats = (...).
So let parse_file return a tuple, and store the tuple in
self.stats.
Then, for example, you can access what used to be called stat3 with self.stats[2].
