Hi Alex, (and hi Ross, since I know you are reading this list),

yes, you can. Here is the trick: Use \scantokens{\POS{...}}

?>*[@_][o]=<0.8pc>{\bigcup} **[|(2)]\dir{-};


Has this trick ever been mentioned in the Xy-pic mailing list? Ross, you 
might want to describe the \scantokens trick somewhere in the Xy-pic 
documentation. It can be a real lifesaver in every TeXnical situation 
where the catcodes have non-default values!
