You haven't actually decided what c is, just that it is some type that is
an instance of the ByteArray class.
:i ByteArray
should show:
instance ByteArray ByteString
instance ByteArray Bytes
instance ByteArray ScrubbedBytes
try
print (c :: ByteString)
print (c :: ScrubbedBytes)

I can't print a byte? _______________________________________________ Beginners mailing list Beginners@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/beginners
