summary

FlashFill++ introduces cut functions, guarded DSLs, and middle-out synthesis to scale programming-by-example to a large DSL with date/time and numeric primitives and to produce idiomatic code for Excel formulas, PowerFx, and Python. It builds an industrial PBE engine that solves 92% of benchmarks versus 65% for the baseline, produces programs about 70% shorter, needs ~0.2 extra examples on average, and rates as more readable in a user study.
