Omit the words least restrictive and I think you are correct.
To combine licences, just aggregate them. There is no lattice of

From what I could determine from a basic Clean introduction, Clean is very

I am profiling a Haskell program using GHC, and after executing the

I would also guess that these are probably the implementations of equality

One way to test this would be to name the equality function explicitly. For
