this is indeed the way to go; for those unfamiliar with the \expanded macro 
(not a primitive): the first thing encountered is *not* expanded, which is 
what one often wants, like in

   \expanded{\somekindofcommand{the stuff to be expanded}

it even works well in cases like:

   \expanded{\somecommand[first not yet expanded arg]}[second already 
expanded arg]

which is more unreadable but faster than

   \expanded{\somecommand[....][...]}

i something should not be expanded inside \expanded, precede it by 
\noexpand (except for the first token)
