object Baz {
class Foo {
private var v = 0
inline def run = {
v += { v = 1 }
v
}
}
val foo = new Foo
foo.run
}but somewhat surprisingly this compiles:
object Baz {
class Foo {
private[this] var v = 0 // or just private var ...
inline def run = {
v += 1
v
}
}
val foo = new Foo
foo.run
}Output (click arrow to expand)
