This defines the name test to be an Int, but what is test? Have you
introduced it earlier? Try instead:

> 1 :: Int


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

You can't do that at the hugs prompt, but you can in a file. In a
command prompt perhaps:

let size = 12+13 in size

Thanks
