Re: [cvs-nhc98] "No default for Main.Class13 at nopos.(861,[(366,865)])"

What does No default for Main.Class13 at nopos.(861,[(366,865)]) mean?

I'm not sure. It might be a cryptic way of saying that the class definition is incorrect.

The class looks like

class Class13 a where class13_1 :: a -> Int class13_2 :: String

This is illegal - all methods of the class must have a type involving the constrained variable a. Regards, Malcolm
