How to put a label after a return statement in Lua?

Question

The following results in a syntax error on the third line:

function f()
    return
    ::x::   
end

Why is it not possible to have a label following a return statement?

Answer 1

A return statement must be the last statement in a block, so just put the return statement in a block:

function f()
    do
        return
    end
    ::x::   
end
