Indy Lambda function names are shuffled

[sellmair]

Given the following example:

fun main() {
    val x = {} // lambda$0
    val y = {} // lambda$1
    val z = {} // lambda$2
}

fun main() {
    val x = { // lambda$2
        val a = {} // lambda$2$lambda$0 
        val b = {} // lambda$2$lambda$1
    }
    val y = {} // lambda$3
    val z = {} // lambda$4
}

It is clear that nested lambdas 'shuffle' names of functions, which will escalate dirty scope resolution (e.g., adding a new nested lambda will invalidate the entire function). This dirty scope invalidation can quickly escalate to the entry point, where reloads will either fail or get rejected (See #218 )

A desirable naming schema for the functions would be

fun main() {
    val x = { // lambda$0
        val a = {} // lambda$0$0 
        val b = {} // lambda$0$1
    }
    val y = {} // lambda$1
    val z = {} // lambda$2
}
