Sam Caldwell	26966b9c34	Implement trie-comprehension macros ... Trie comprehensions abstract the process of projecting one-or-more tries against some patterns, binding the results to usable variables, and iterating over the results. Currently supports for-trie/fold, for-trie/list, for-trie/set, and for-trie/patch, as well as the ability to easily create new trie comprehension macros. Note that these comprehensions operate in the style of `for*` rather than `for`.	2016-02-05 13:27:20 -05:00
