> Can we lift the restriction on using 'var' on the main branch? I know it's a
> double-edged sword and sometimes it leads to unreadable code, especially when
> you invoke a method, for example:
> {code}
> var foo = myMethodThatDoesSomething();
> {code}
> but in many, many, *many* cases the var keyword shortens the code and the
> type is obvious from the context. This happens in loops, try-with-resources
> and local variables.
> {code}
> for (var it = array.iterator(); it.hasNext();) { ... }
> try (var foo = new MyFoo()) { ... }
> {code}
> I'd say - let's allow vars (and other language features) and use common
> sense. If something is not clear in the context, type the variable. If
> something is obvious, use shortcuts.
