/* Test Struct productions

Run with --test to generate an AST and verify that all comments accurately
reflect the state of the Nodes.

BUILD Type(Name)
This comment signals that a node of type <Type> is created with the
name <Name>.

ERROR Error String
This comment signals that a error of <Error String> is generated.  The error
is not assigned to a node, but are expected in order.

PROP Key=Value
This comment signals that a property has been set on the Node such that
<Key> = <Value>.

TREE
Type(Name)
  Type(Name)
  Type(Name)
    Type(Name)
    ...
This comment signals that a tree of nodes matching the BUILD comment
symatics should exist.  This is an exact match.
