Is it ever advantageous to use 'goto' in a language that supports loops and functions? If so, why?
...uch cleaner and simpler than break statements and if-checks.
Low-level performance improvements
This is only valid in perf-critical code, but goto statements execute very quickly and can give you a boost when moving through a function. This is a double-edged sword, however, because a compiler typ...
prototype based vs. class based inheritance
...same state space (read "possible values") and the same operations, thereby forming an equivalence class. If you look back at Smalltalk, since you can open a class and add methods, this is effectively the same as what you can do in Javascript.

What are the main purposes of using std::forward and which problems it solves?
...type “rvalue reference to cv TR” creates the type TR."
Or in tabular form:

T& && -> T& // rvalue reference to cv TR -> TR (lvalue reference to T)
T&& & -> T...
Why does Python print unicode characters when the default encoding is ASCII?
...se a code point's value in the Unicode map as its value for its electronic form, but Unicode currently has over a million code points, which means that some of them require 3 bytes to be expressed. To work efficiently with text, a 1 to 1 mapping would be rather impractical, since it would require th...

What is uint_fast32_t and why should it be used instead of the regular int and uint32_t?
...
int may be as small as 16 bits on some platforms. It may not be sufficient for your application.
uint32_t is not guaranteed to exist. It's an optional typedef that the implementation must provide iff it has an unsigned integer type of exactly 32-bits. Some have a 9-bi...

How does type Dynamic work and how to use it?
... do something like
val name = "foo"
d.$name
where d.$name would be transformed to d.foo at runtime. But this is not that bad because even in dynamic languages this is a dangerous feature.
Another thing to note here, is that updateDynamic needs to be implemented together with selectDynamic. If we...
