[boost] BGL: checking for internal properties

Jeremy,

suppose I got lazy and don't want my graph algorithm to be passed a graph
which does not have internal edge_weight property. What's the best way to
check? I can do

    get(edge_weight, g);

but that causes compile error in instantination deeps. What I'd like is 
something like:

     BOOST_STATIC_ASSERT(has_property<edge_weight_t, G>::value);

Is it possible now? If not, is this a reasonable feature?
