[racket] match in Advanced Student?

Why does this expression successfully evaluate in #lang racket but gives 
a syntax error in Advanced Student?

(match 1
   [(or 1 2) 'pass]
   [else 'fail])

The or-clause is highlighted and the error is "match: expected a 
pattern, but found a part".

Thanks. --PR
