For the purpose of implementation, nested parentheses (called parens) can represent boundary logic containers. However, it is also necessary to address specific nested component containers, particularly for circuit optimization. The pun data structure facilitates the construction, deconstruction, and rearrangement of component parens forms.

Examples of Usage

Circuit Design Generation –– The following pieces use a single small circuit
(CM85A -- a 4-bit magnitude comparator with enables) to illustrate ILOC goal-directed transformations of the pun data structure, resulting in over 30 different design varieties that meet various desirable optimization criteria.
