bolt/rules/correctness/strings.bend fails

raw source on the hub · import 0x729eecea86ea5a2cdba3a2856a313bca/bolt/rules/correctness/strings.bend as Strings

rule strings: a match whose arms are string literals (case "foo":) with more than 64 literal characters in all. Each string arm lowers into nested per-char tests, and the checker's time and memory grow with the characters (bend 2.0.16: 45 characters take 0.8 s and 0.35 GB, 100 take 2 s and 1 GB, 480 take 12 s and 4.8 GB; pi-bend BEND-001/016 was 16 long event names). The number of arms barely matters, so only the characters count. Classify the string once through a lookup table into a sum type, and match on that.
