object Foo {
var initialized = 0
// This only happens once regardless of how many times Foo.fetch() is called
initialized = initialized + 1
def fetch(): Integer = initialized
}
class Foo {
println(s"initialized: ${Foo.fetch()}")
}
new Foo // prints "initialized: 1"
new Foo // prints "initialized: 1"
new Foo // prints "initialized: 1"
