This turns splices that are ignored into compiler errors. Other alternatives here should also be considered, for example making this a compiler warning rather than an error. For example, the latest spork as of a3ee63c137ee3234987dbbca71b566994ff8ae8c has an error of this kind, but the resulting program does work correctly. Also disallow splice propagation - code of the form (+ 1 (do ;[2 3 4]) 5).
