I'd like to see IncPy and SlopPy combined so one could iteratively fix the causes of the exceptions passed by SlopPy, this would also require some Incremental Computation, see Acar et. al
yep great idea. one of my pipe dreams was to combine all of those systems into one giant uber pipeline for data science ... but then i finished my Ph.D. and moved on to other things :)
