exemplify-align

Exemplify-Align aligns the arrowheads of Exemplify-ERT–like examples.

From:
  #s(hash-table test equal data (:a 1))         H==> (h* :a 1)
  (* 6 7)         => 42
  (concat "a" foo "b")  !!> void-variable

To:
  #s(hash-table test equal data (:a 1)) H==> (h* :a 1)
  (* 6 7)                                 => 42
  (concat "a" foo "b")                   !!> void-variable

(As for *creating* these examples in the first place, you may find that
easier with the package Exemplify-Eval.)
