jhc Temp/jhc1.hs jhc 0.8.2 (mydniquipepo-32) Finding Dependencies... Using Ho Cache: '/home/yom/.jhc/cache'
Temp/jhc1.hs:1 - Error: Invalid Class. multiparameter classes not yet supported: (Num,[HsTyTuple [HsTyVar {hsTypeName = a},HsTyVar {hsTypeName = b}]])
Am I misunderstanding something, or is it a legitimate bug?
Looks multiparameter to me: instance ... => Num (T a b Int) where with T ~ (,,). Which is what the second line of the error message is telling you, more or less. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
