You type about the same number of characters. Now imagine you wanted to declare the value to be immutable.

  Its 5 extra characters actually.. because any sensible C++ project has i32 etc defined. The type omission version isn't very useful, as this type of code is difficult to read later. Generally end up regretting using auto, and end up converting it to the actual type, except with iterators or nasty templates.

    That hasn't been my experience, personally. In fact, sometimes I wish decltype was easier to use, to declare type dependencies.

  That's only true because they used build-in int type. Why would I prefer to use: var inst : MyClass; over MyClass inst;
