\(\log_* (1 + x)\)
  1. Started with
    \[\log \left(1 + x\right)\]
    16.6
  2. Applied simplify to get
    \[\color{red}{\log \left(1 + x\right)} \leadsto \color{blue}{\log_* (1 + x)}\]
    0.0
  3. Removed slow pow expressions

Original test:


(lambda ((x default))
  #:name "ln(1 + x)"
  (log (+ 1 x))
  #:target
  (if (= (+ 1 x) 1) x (/ (* x (log (+ 1 x))) (- (+ 1 x) 1))))
