Yes, the problem is the operator precedence.
If the function consists of one expression you can use parenthesis instead of
curly braces.
If you're using curly braces, you don't need the parenthesis around the
argument: { ns: NodeSeq => ...

Well, it would help to have the compiler error, but I may have gotten
precedence wrong. Try:
"expand" -> { (fooXhtml: NodeSeq) => ... }
instead
