Ref cursor argument in where clause

Question

Env: ORCL 9.2
I have a func that uses the parameters in a where clause and returns a ref cursor as result. That works fine.
I want to create an overloaded func that replaces one argument with a ref cursor. (instead of accepting a single value as an argument I want to accept multiple values) Can you specify the ref cursor in a where clause with out looping through the cursor ?
CURRENT
func(arg1,arg2,arg3) returns ref cursor
is
select blah from sometable s
where s.a = arg1
and s.b = arg2
and s.c = arg3
NEW
func(ref_cur_arg1,arg2,arg3) returns ref cursor
is
select blah from sometable s
where s.a = ref_cur_arg1
and s.b = arg2
and s.c = arg3
is there something like:
where s.a in (loop fetch ref_cur_arg1 end loop)
thx

Thanks Rich,
That's pretty much what I came up with:
FUNCTION f_bond_price_w_bb_stat (
                              p_id_ref gtyp_instr_id_ref,
                              p_price_srce bond_price.PRICE_SRCE%type,
                              p_price_type bond_price.PRICE_TYPE%type,
                              p_price_date bond_price.PRICE_DATE%type)
RETURN gtyp_bondprice_w_bb_stat_rfc
IS
lv_bondprice_rfc gtyp_bondprice_w_bb_stat_rfc;
TYPE ARRAY1 IS TABLE OF instr_ext_id_map.ext_id_value%TYPE INDEX BY BINARY_INTEGER;
t_instr_id ARRAY1;
instr_ids INSTR_EXT_ID_T := INSTR_EXT_ID_T();
BEGIN
     --suck the contents of the ref cursor into a local virtual tmp table
FETCH p_id_ref BULK COLLECT INTO t_instr_id;
FOR i IN 1..t_instr_id.COUNT LOOP
     instr_ids.extend;
          instr_ids(instr_ids.count) := t_instr_id(i);
END LOOP;
CLOSE p_id_ref;
OPEN lv_bondprice_rfc FOR
SELECT
bs.ID_ISIN,
bs.TICKER,
bs.CPN,
bs.MATURITY,
round(months_between(bs.MATURITY,sysdate)/12,1),
bs.ISSUER_INDUSTRY,
bs.INDUSTRY_SECTOR,
FROM bond_price b,
instr_ext_id_map ext,
etl.mdy_ratingstatic mrs,
     etl.mdy_extid mxid,
     etl.bloomberg_static bs
WHERE b.INSTR_ID = ext.instr_id
AND bs.ID_ISIN(+) = ext.ext_id_value
AND bs.ID_ISIN = mxid.EXTIDVALUE(+)
AND mrs.MOODYDEBTNUM(+) = mxid.MOODYDEBTNUM
AND ext.ext_id_value in (select * from TABLE (cast (instr_ids AS INSTR_EXT_ID_T) ))
AND b.PRICE_SRCE = p_price_srce
AND b.PRICE_TYPE = p_price_type
AND b.PRICE_DATE = p_price_date
RETURN lv_bondprice_rfc;
END f_bond_price_w_bb_stat;
