Hi all! Some days ago we were talking here about `suspend` functions that, in Arrow Fx, could be defined "pure" as their side effects are suspended until the "end of the world". But I was wondering about referential transparency of this kind of functions; I concluded that `suspend` functions are referentially transparent only when wrapped inside an `effect {}` block; instead, when a `suspend` function is called from another `suspend` function, it isn't. An example is the following:
```
suspend fun readNumberFromConsole(): Int = TODO("Side effect that returns an integer")

suspend fun example1(): Int {
    val x = readNumberFromConsole()
    return x + x;
}

suspend fun example2(): Int {
    return readNumberFromConsole() + readNumberFromConsole()
}
```
What do you think about this? Could this be a bit misleading when writing functional code?
