Walkthrough

Renames and small refactors across exercise templates: one test package renamed, several time-delay template functions renamed to their final exported names (implementations remain TODO), removal of an unused sync import/WaitGroup, and a relaxed timing assertion in a worker-pools test.

Changes

Cohort / File(s)	Change Summary
Package rename internal/exercises/templates/39_panic/panic_test.go	Package declaration changed from package exercises to package panicex.
Time-delay API renames internal/exercises/templates/41_time_delay/time_delay.go	Multiple template function names and signatures renamed to final exported forms (e.g., WaitForTemplate → WaitFor, NotifyAfterTemplate → NotifyAfter, ScheduleAfterTemplate → ScheduleAfter, ElapsedMillisTemplate → ElapsedMillis, etc.). Implementations remain TODO.
Wait-group cleanup internal/exercises/templates/42_wait_group/wait_group.go	Removed sync import and an unused WaitGroup variable from Squares; function still returns nil.
Test timing relaxation internal/exercises/templates/43_worker_pools/worker_pools_test.go	Increased allowed upper bound for a timing assertion in TestLogProcessor (now up to ~1400μs) with comment explaining flakiness/observed max.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Multiple related but distinct edits across 4 files; mostly straightforward renames and a minor test tweak.
• Areas to pay attention to:
  • Ensure package rename in panic_test.go matches any other test or package references.
  • Confirm time-delay function renames are consistent with callers elsewhere in the repo (public API change).
  • Verify removal of sync and wg does not affect other logic or expected concurrency behavior.
  • Check test timing change is intentional and doesn’t mask real regressions.

Poem

🐇 I hopped through code at break of day,

Renamed a package, tuned delays to play,
I trimmed a WaitGroup and loosened a test,
Little changes — but I feel blessed! 🎈
