The DOM is stupid. It has appendChild and insertBefore, but no prependChild and insertAfter.

So we should just walk the DOM back to front.

We will deal with fragments. A Fragment can contain a variable number of nodes, 0 or more.

• seq() creates a fragment with 0 or more nodes
• match() creates a fragment with 0 or 1 node
• children creates a fragment with 0 or more nodes

this follows the estree format

interface Fragment <: Node {
  type: "Fragment";
  body: [
    Component | Tag | Block | Conditional | Iteration |
    Expression // Any JS  Expression
 ]
}

// The data structure of your favorite data structure libary.
// Might just be a plain JS Object. Keys are guaranteed to be Strings
DataMap = Any

// The library should be agnostic to what kind of data library is used,
// therefore every kind of data access should go through this interface
Data = {
  // Creates a new Map, optionally with an initial JS object provided
  create: (Object?) => DataMap,
  // Used to retrieve a key, for example from the `Context`.
