[Hugs-users] '=' and ':' generate errors

[Dave at haskell.org]

running Hugs98 sept 2006 version, on AMD 64-bit OpenBSD 4.0,

test :: Int
ERROR - Undefined variable "test"

size = 12+13
ERROR - Syntax error in input (unexpected `=')

These lines are right out of _The Craftf of Functional Programming_,
2nd Edition, which I just received in the mail.

Is Hugs98 broken on my system?

Thanks,
Dave Feustel
