Wesley W. Terpstra 52bb6cd9d9 Configs: use a uniform syntax without Match exceptions (#507) ... * Configs: use a uniform syntax without Match exceptions The old style of specifying Configs used total functions. The only way to indicate that a key was not matched was to throw an exception. Not only was this a performance concern, but it also caused confusing error messages whenever you had a match failure from a lookup within a lookup. The exception could get handled by an outer-lookup that then reported the wrong key as missing.		2017-01-13 14:41:19 -08:00
