Test "std"

Expected: 👍 accept · Size: 526.1 MB · Lines: 10.0 M · lean4export: 3.1.0 · Lean: 4.29.0 · 📄 Declaration · 🔗 Source

The complete Std library export from Lean 4.

This test contains the standard library extensions beyond core Lean 4, including:

  • Enhanced data structures (HashMap, RBTree, etc.)
  • Additional mathematical operations
  • Extended list and array operations
  • Utility functions and theorems

This represents a medium-sized test case, larger than core modules but smaller than Mathlib, making it useful for performance testing.
