If there is no model expansion could it be because of the constructor discipline, which only allows variables, and constructors in the LHS argument patterns.
Indeed, a variable name as a pattern on the LHS of a function definition has nothing to do with any names which might be in scope. It is simply a pattern which matches anything. I am not sure what (if anything) this says about model expansions.
constant::Int constant = (1::Int) fun1::Int -> Int fun1 (constant::Int) = 8
fun1 returns 8 for all inputs. The fact that fun1's definition uses the name 'constant' which happens to have the same name as something in scope is irrelevant. For example, this is precisely the same as the above: constant :: Int constant = 1 fun1 :: Int -> Int fun1 foo = 8 -Brent
