Do I need a trailing semicolon to disambiguate this code?

Question

If I omit the semicolon, this code doesn\'t compile.

def checkRadioButton(xml: DslBuilder): String => XmlTree = {
    val inputs = top(xml).\\\\*(hasLocal         


        

Answer 1

Just add a second newline, which apparently is equivalent to the semicolon.

Still, I'm not entirely happy with this, as it seems fragile.
