I think the first time I saw gerund insert, Ken Iverson showed off

   +`%/10# 1x

13r8


getting Fibonacci approximations to the Golden ratio, so I always expected it to be "from the front".


Seeing this thread, I decided to experiment but forgot to "insert" and got something unexpected:


   +`* i.3

2

   +`* 0 1 2

|syntax error

| +`*0 1 2


   +`* i.33

2

   +`*`-`- i.33

4

Gerund applied to i. gives the length of the gerund?!
