Thanks for explaining the empty label.

About goto "", I've just noticed that $u= ""; goto $u; does not have this wierd beheaviour (it dies with the correct message), so maybe goto ""; isn't a computed goto at all. Notice that a computed last is illegal, but last "label"; or even last ("label".""); does work, as ("label"."") is a constant expression.
