Order of declaration in top level

[yadavan88]

Hi,
While I was trying the scala 3 features, found out a behaviour which I thought is interesting or strange. Is this expected behaviour?

`
val i = j + 100
val j = 10

@main def main() =
println("i="+i) // prints 100, but was expecting 110
println("j="+j)
`

I thought it might give forward reference error, but instead it computed by using the default value.

This is also a frequent question with the (Scala 2) repl. That is, semantics depends on the underlying implementation or model.

I think this is worth nailing down, even if the REPL and compiler must distinguish "newbie" mode from "expert" mode.

In this case, -Ycheck-init is your friend.

Arguably, the compiler could offer a "development" mode, that would be orthogonal to optimizer flags, for example. Possibly sbt could respect development mode (and do a clean build on publish, for example).

Thanks for the quick reply. I accidentally got this issue when I used the shortcut to move up the line in IDE. I was confused why the simple + was printing wrong value.
