Implements the copy-if pattern as a Lean tactic: - 'copy_if' tries rfl → decide → omega → norm_num → simp in order - 'copy_if?' reports which closer worked (for profiling) - Each closer is a 'zero delta' check — if goal is in normal form, closes instantly; if not, tries next closer This is the Lean-native equivalent of: - Blog post: vpcompressd register-dest = 40x faster - VCN: numpy copy-if = 3.3x faster - Pre-filter: skip trivial theorems = 2.7x faster - LSP: copy_if tactic = instant close for zero-delta goals Usage: import Semantics.CopyIfTactic theorem foo : 1 = 1 := by copy_if theorem bar : x + 0 = x := by copy_if theorem baz : complex := by copy_if -- falls through to simp 3298 jobs, 0 errors. Tests pass for rfl, decide, omega, norm_num. |
