I see some no's, but can anyone add an argument? Java does support it, and the only argument I found for Kotlin to ditch it, is that implicit type conversion could lose precision. By making it explicit to allow this conversion, you give back the option to the developer, and make the code more dynamic. In the example above I could just change myInt to double or String without modifying the explicit conversion (toInt)

I'll add that Kotlin was designed to avoid Java's mistakes. One of the biggest flaw of Java is to implicitely convert `Integer`s to `int`s (auto-unboxing). In case an

Integer

is

null

, implicitly unboxing it would cause a very hard to find

NullPointerException

.
