精彩摘录

"......create softerware that's correct efficient maintainable portable"
"C++98 had a single set of rules for type deduction: the one for function templates. C++11 modifies that ruleset a bit and add two more, one for auto and one for decltype. C++14 then extends the usage contexts in which auto and decltype may be employed."
"When users of a complex system are ignorant of how it works, yet happy with what it does, that says a lot about the design of the system. By this measure, template type deduction in C++ is a tremendous success."
"The ability to declare references to arrays enables creation of a template that deduces the number of elements that an array contains."
"The only real difference between auto and template type deduction is that auto assumes that a braced initializer represents a std::initializer_list, but the template type deduction doesn't."
"In C++11, perhaps the primary use for decltype is declaring function templates where the function's return type depends on its parameter types."
"The use of "decltype(auto)" is not limited to function return type. I can also be convenient for declaring variables when you want to apply the decltype type deduction rules to the initializing expression."
"Employing pass-by-value for objects of an unknown type generally risks the performance hit of unnecessary copying, the behavioral problems of object slicing, and ..."
