-- AST Node Interface.

-- implemented by `Value` and `Cell`.
--
-- @classmod AST
--- members
-- @section members
--- evaluate this AST Node.
--
-- Evaluate this node and return a `Result`.
--
-- @class function
-- @name eval
-- @tparam Scope scope the scope to evaluate in
-- @treturn Result the evaluation result
--- quote this AST Node, preserving its identity.
--
--- Returns a mutable copy of this Node that shares its identity.
--
-- @class function
-- @name quote
-- @treturn AST
--- create a clone with its own identity.
--
-- creates a clone of this Cell with its own identity by prepending a `parent`
-- Tag (and cloning all child expressions recursively).
--
-- @class function
-- @name clone
-- @tparam Tag parent
-- @treturn AST
--- stringify this AST Node.
--
-- Should return the exact string this node was parsed from (if it was parsed).
