How rewrite without '::' ?

[François Perrad]

the PMC equivalent of the following PIR :
     $P0 = new 'Foo::Bar'
is like :
     INTVAL type = pmc_type(INTERP, const_string(INTERP, "Foo::Bar"));
     PMC *pmc = pmc_new(INTERP, type);

Now, how rewrite
     $P0 = new ['Foo'; 'Bar']

     INTVAL type = pmc_type_p(INTERP, ??? any idea ???);
     PMC *pmc = pmc_new(INTERP, type);
