Description

The documentation for the omegaDefault tactic gives a broken example for aesop usage.

Context

I tried to use omega with aesop but the documentation example was not valid. It says:

/-- The `omega` tactic, for resolving integer and natural linear arithmetic problems. This
`TacticM Unit` frontend with default configuration can be used as an Aesop rule, for example via
the tactic call `aesop (add 50% tactic Lean.Omega.omegaDefault)`. -/

but this does not work:

import Aesop

example : 1 = 1 := by
  aesop (add 50% tactic Lean.Omega.omegaDefault)

Steps to Reproduce

1. Code as above

Expected behavior: Example tactic call succeeds.

Actual behavior: Example tactic call fails.

Versions
