+Surrounding a tactic with `skip_proof` will skip running the tactic and close the goal with `skipProofAx`.
+We only skip proofs if `skip_proof.skip` is set to `true`,
+and we emit a warning to remind the user that proofs are being skipped.
+
+This is to be used, during development, with expensive tactics such as `omega`, `bv_omega`, `bv_decide`, `simp_mem`.
+This allows one to run `have expensive_hyp : ... := by omega`, check that this can be proven,
+and to then replace this with `have expensive_hyp : ... := by skip_proof omega`.
+This will skip the use of `omega`, and instead use `skipProoxAx`.
+This ensures that Lean stays performant during interactive development.
+
+`skip_proof p` signals that when `set_option skip_proof.skip false` is set, the proof `p` *will go through*.
+This makes `skip_proof p` morally different from a `sorry`:
+- It still retains the proof `p`. This signals the intent of a completed proof that has been skipped for performance.
+- It uses a different axiom (`skipProofAx` instead of `sorryAx`).
+  This allows `#print axioms in thm` to distinguish between skipped proofs and genuine `sorry`s.
