Expr[T, N] is an expression of a graph of container nodes N[_] with result type N[T]. These expressions are like the Literal[T, N] graphs except that functions always operate with an indirection of a Id[T] where N[T] is the type of the input node.
Nodes can be deleted from the graph by replacing an Expr at Id = idA with Var(idB) pointing to some upstream node.
To add nodes to the graph, add depth to the final node returned in a Unary or Binary expression.
TODO: see the approach here: https://gist.github.com/pchiusano/1369239 Which seems to show a way to do currying, so we can handle general arity
