Module: Cardname::Pieces

Included in:
Cardname
Defined in:
cardname/lib/cardname/pieces.rb

Overview

Cards never have more than two “parts” (left and right), but they can have many “pieces”. A card’s pieces are all the other cards whose existence its existence implies. For example if A+B+C exists, that implies that A, B, C, and A+B do too.
