This is a manifestation of the Monomorphism Restriction, invoked because lst doesn't take any arguments: it forces lst to have a definite type, so defaulting is used to fix the numeric part to Integer. If you add a type specification for lst, things will work as you expect. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] [email protected] administrator [openafs,heimdal,too many hats] [email protected] and computer engineering, carnegie mellon university KF8NH
