I haven't done it before, since this macro is pretty easy:
#macro InObj(Pt, Obj) eval_pattern(object {Obj}, Pt) #end

But all it should take is adding a "inside_object" token to parse.h and 
tokenize.c, and adding this case to Parse_Num_Factor() in express.c 
(make sure you put it with the float functions):
          case INSIDE_OBJECT_TOKEN:
          {
            OBJECT * Object; 
            VECTOR Point;

            GET(LEFT_PAREN_TOKEN);
            Parse_Vector(Point);
            Parse_Comma();
            EXPECT
                CASE(OBJECT_ID_TOKEN)
                    Object = Token.Data;
                    EXIT
                END_CASE
                OTHERWISE
                    Object = NULL;
                    UNGET
                    EXIT
                END_CASE
            END_EXPECT
            if(Object == NULL)
            {   Error ("Object Identifier Expected.");}
            GET(RIGHT_PAREN_TOKEN);
            
            Val = Inside_Object(Point, Object);
          }
          break;

I haven't tested this patch (I haven't even compiled it), but it should 
work.
