Summary: PF: pf:mil() prints garbage if MIL result is 'nil'
Initial Comment:
If the evaluation of the MIL code passed to pf:mil() results in a 'nil' value,
pf:mil() will print garbage:
xquery>pf:mil('var a := new (void,oid);')
more><>
""
I think the problem is in the MPS translation of pf:mil():
{ # translate pf:mil (string) as item*
if (count(loop000) != 1) ERROR("pf:mil cannot be called from within a for-
loop");
kind := ELEM;
item := ws_mil(ws, item_str_.fetch(0));
if (type(item) = str) {
item := addValues(str_values,item);
kind := STR;
}
kind := set_kind(WS,kind);
iter := item.materialize(ipik).project([EMAIL PROTECTED]);
ipik := iter;
} # end of translate fn:mil (string) as item*
Note that the return value of ws_mil is not checked if it is a 'nil'.
