    W.r.t. an earlier comment about methods in nested scopes: It is already checked
    that the gf is in the same scope. It actually enforces that the corresponding
    function is in the same scope, too, which might be unnecessarily restrictive.
    Compilation works fine. Also, I discovered that it is possible to invoke a
    nested gf that has a single, default method; it gets compiled to a direct
    function call, which works. This special case is sufficient for Cecil's
    closures (although not Diesel's), ignoring lexical scoping issues.
