Why the switch statement cannot be applied on strings?
...tem. C/C++ doesn't really support strings as a type. It does support the idea of a constant char array but it doesn't really fully understand the notion of a string.
In order to generate the code for a switch statement the compiler must understand what it means for two values to be equal. For ...
make_unique and perfect forwarding
...c type checking (which is the main diff between C++ and C) is built on the idea of enforcing safety, via types. And for that, make_unique can simply be a class instead of function. For example, see my blog article from May 2010. It's also linked to from the discussion on Herb's blog.

What is the Scala annotation to ensure a tail recursive function is optimized?
...is actually not tail-recursive. This makes the @tailrec annotation a good idea, both to ensure that a method is currently optimizable and that it remains optimizable as it is modified.
Note that Scala does not consider a method to be tail-recursive if it can be overridden. Thus the method must ei...
Can I assume (bool)true == (int)1 for any C++ compiler?
... C syntax in general. Nevertheless, it is, of course, almost always a bad idea to redefine language keywords.

Behaviour of increment and decrement operators in Python
...rser won't be more complex than LL(1). Simple is better than complex. This idea extends to the parser. Restricting Python's grammar to an LL(1) parser is a blessing, not a curse.
