    12 
    12   constants declared in the same theory;
    13 * Provers/Arith/fast_lin_arith.ML contains a functor for creating a decision
    13 
    14 procedure for linear arithmetic. Currently it is used for types `nat' and
       
    15 `int' in HOL (see below) but can, should and will be instantiated for other
       
    16 types and logics as well.
