I gave up following the other goto thread so I must have missed the "per 
function" label constraint.  It should really be "per block".

Its ashame. The goto syntax isn't easy on the eyes, but it was powerful 
and allowed a reasonable workaround for standard patterns like continue. 
 But this "per function" limit really blows that; what a pity.
