class Element x i where

During construction of the stream, we need to extract individual elements from symbols in production rules. An element in a stream is fixed by both, the type x of the actual argument we want to grab (say individual characters we parse from an input) and the type of indices i we use.

Elm data constructors are all eradicated during fusion and should never show up in CORE.

class Monad m => MkStream m x i where

mkStream creates the actual stream of elements (Elm) that will be fed to functions on the left of the (<<<) operator. Streams work over all monads and are specialized for each combination of arguments x and indices i.

class Build x where

Finally, we need to be able to correctly build together symbols on the right-hand side of the (<<<) operator.

The default makes sure that the last (or only) argument left over is correctly assigned a Z to terminate the symbol stack.
