Thanx, Jenda and Japhy.
Damn... I put it as @{ $FUNC{$pkg_func} } but strict complained about it not
being declared.
I see now that I need the -> arrow.
So when is it safe to say stuff like
$$ref
@$ref
??
I have used it with
$$onediminsional_hash_ref{$key}
@$onediminsional_array_ref[$index]
I guess it doens't work with multidimensional data structures?
