Summary brace-expansion's expand exhibits exponential-time - O2ⁿ - behavior in the number of consecutive non-expanding groups. A short, all-ASCII input 90 bytes/30 groups blocks the calling thread for minutes; a slightly longer input hangs it effectively indefinitely. Because the dominant consume...
