Guaranteed lifetime of temporary in C++?
Does C++ provide a guarantee for the lifetime of a temporary variable that is created within a function call but not used as a parameter? Here's an example class:

Yes, You should.
And you should use C++ instead of C# because of performance. C# is for lazy people.

The key difference between Python's semantics and C++ pass-by-reference semantics is that assignment is not mutation in Python, and it is in C++. (But of course that's complicated by the fact that augmented assignment, like a += b sometimes is mutation. And the fact that ass...

Do try/catch blocks hurt performance when exceptions are not thrown?
...ll here,
by which I mean the static cost can be
much lower than say in C++. Why is

incurred in two kinds of places:
First, the actual sites of
try/finally/catch/throw where there's
code for those constructs. Second, in
unmanged code, there's the st...
