A fresh Scott Meyers post about a brand-new C++14 feature:

When decltype meets auto

by Scott Meyers

... C++14 is on the horizon, and one of the new features sure to stifle even the strongest of yawns is the ability to declare types using decltype(auto). This feature leads to two questions, only the first of which is rhetorical:

1. You can declare what?
2. During type deduction for decltype(auto), which type deduction rules are to be followed: those for auto or those for decltype? Or does decltype(auto) have its own set of type deduction rules?
