Tree-list-list

True lists of true lists of trees of rule names and terminal values.

As explained here, these are the outer lists that correspond to concatenations.

Subtopics

Tree-list-listp

(tree-list-listp x) recognizes lists where every element satisfies tree-listp.

Tree-list-list-equiv

Basic equivalence relation for tree-list-list structures.

Tree-list-list-fix

(tree-list-list-fix x) is a usual ACL2::fty list fixing function.
