A compound declaration allows us to declare a group of variables of the same type without repeating the type. The type is specified a single time and the variables are demarcated by a comma:

// using explicit type
String pending = "pending", processed = "processed", 
       deleted = "deleted";

Replacing String with var will result in code that doesn't compile:

// Does not compile
var pending = "pending", processed = "processed", deleted = "deleted";

The solution to this problem is to transform the compound declaration into one declaration per single line:

// using var, the inferred type is String
var pending = "pending";
var processed = "processed";
var deleted = "deleted";

So, as a rule of thumb, LVTI cannot be used in compound declarations.
