}

Why doesn't the example compile, aka how does (co-, contra-, and in-) variance work?
...ranslating their example to use your construct:
val x = new Slot[String]("test") // Make a slot
val y: Slot[Any] = x // Ok, 'cause String is a subtype of Any
y.set(new Rational(1, 2)) // Works, but now x.get() will blow up

'typeid' versus 'typeof' in C++
...icy, but as the question is tagged C++ I would expect it to refer to the latest standard. Retagging the question as C++03 would also be an option imho. I personally get quite confused sometimes, as I have to use preC++11 at work and sometimes I am not sure what is true "pre11" or "post11".

Mentioned before Column stores look like good fit for relations.. but it all depends on your A and C and P needs;) If you do not need A and you have less than Peta bytes just leave it, go ahead with MyS...

Why does 'continue' behave like 'break' in a Foreach-Object?
...($_) is a multiple of 7"}}
But a more elegant solution is to invert your test and generate output for only your successes

What is the rationale for all comparisons returning false for IEEE754 NaN values?
... Theoretically, if you had NaN == NaN and no isNaN, you could still test for NaN with !(x < 0 || x == 0 || x > 0), but it would have been slower and clumsier than x != x.
