Barna Kovacs landed three optimization PRs removing dead code from core Enum and Calendar modules, while a separate fix addresses a flawed tuple projection algorithm that was producing inconsistent type representations.

The stdlib cleanup pushed by Kovacs across Enum.drop/2 [1], Date.Range [2], and Calendar.ISO [3] eliminates guard clauses and abs calls that were logically unreachable given preceding conditions. These aren't micro-optimizations; they're clarity wins that make the actual logic path obvious to anyone reading the code. Separately, a rework of the tuple projection algorithm [5] fixes a deeper issue: the previous basis was 'creating errors (different representations of the same type gave different results)' [5], surfaced in issues #15606 and #15491. The new implementation corrects both, with regression tests baked in. IEx also shed stale baggage with the removal of the :three_op operator [4], cleaning up evaluator state. Across both desks: 11 commits and 11 PRs landed. This is the kind of round where the stdlib gets healthier without breaking anything.

Action items

→ Pull the latest elixir-lang/elixir to pick up the tuple projection fix if you've hit inconsistent type representations elixir-lang/elixir [plan]
→ Review the tuple projection changes if you maintain type-checking or validation code that depends on consistent range behavior elixir-lang/elixir [monitor]
