This patch is actually an amalgam of multiple (already large) patches. Those patches conflicted (parameterised Structured vs. changes to usage checking and FlowGraph) and encountered a nasty bug in darcs 1 involving exponential time (see http://wiki.darcs.net/DarcsWiki/ConflictsFAQ for more details). Reasoning that half an hour (of 100% CPU use) was too long to apply patches, I opted to re-record the parameterised Structured changes as this new large patch. Here are the commit messages originally used for the patches (which, as mentioned, were already large patches): A gigantic patch switching all the non-test modules over to using parameterised A.Structured Changed the FlowGraph module again to handle any sort of Structured you want to pass to it (mainly for testing) A further gigantic patch changing all the tests to work with the new parameterised Structured Fixed a nasty bug involving functions being named incorrectly inside transformInputCase Added a hand-written instance of Data for Structured that allows us to use ext1M properly Fixed a few warnings in the code
