Are there differences between REPL and source code?:

// source code
fun main(args: Array<String>) {
    val value: Int
    value = 3
}

// REPL
>>> val value: Int
error: property must be initialized or be abstract
val value: Int

yes, inside the source code the compiler sees that value is initialized in the next line, inside the REPL it can't tell if you'll initialize it in the next line or use it without initializing it

Thanks @Andreas Sinz!!
