{
var x = 0
var y = 0

Open a new scope:

class Test(n: Int) {
var x = 0

{
var i = 0
while (i < n) {
x = x + i
i = i + 1
}
}
def test =
println(x)
}

Note the extra line of whitespace between var x = 0 and the scope; either an extra line or a semicolon is necessary to keep
the block from being interpreted as a refinement.
