Error when compiling tests/list.an

To update this:

The error message on the latest version of master is

23,12-17 error: Invalid type cast i32 -> List
var head = List 0

A little bit of debugger diving got me to the point where the type system attempts to compare the type variable of List with the tuple wrapper of i32, and the result of getBindingFor gives a strange-looking TypeNode which takes its type name from the name of the elem variable.
