summary

Implements a tool called EasySpec that generates QuickSpec signatures from GHC metadata, runs QuickSpec repeatedly on tiny chunks of relevant functions, and unions results to recover properties much faster than a single global run. Claims are several orders of magnitude faster (examples: a 15‑function run that used to take minutes drops to seconds) and produces similar equations. Works on examples; practical gaps remain (C preprocessor, scoping, false positives require manual vetting).
