... began with the move semantics. Once we have expressions that can be moved and not copied, suddenly easy to grasp rules demanded distinction between expressions that can be moved, and in which direction. From what I guess based on the draft, the r/l value distinction stays the same, only in the con...

...of 11.4. Now, a little explanation into why this is happening: The float and double primitive types in Java are floating point numbers, where the number is stored as a binary representation of a fraction and a exponent. More specifically, a double-precision floating point value such as the double...

...n doubt, use a pointer." Slices, maps, channels, strings, function values, and interface values are implemented with pointers internally, and a pointer to them is often redundant. Elsewhere, use pointers for big structs or structs you'll have to change, and otherwise pass values, because getting thi...
