I suspect the parallel assignment is damaging (or at least confusing)
matters. Having a gerund is having a noun. One needs to evoke it
one way or another e.g. `:6) to get a verb back.
Consider
g=:+/`%`#
sum=:0{g
div=:1{g
count=:2{g
mean=.(sum ,div, count)`:6
mean 2 3 4 7
4
Or
erase'mean sum div count'
1 1 1 1
mean=.sum div count
sum=:(0{g)`:6
div=:(1{g)`:6
count=:(2{g)`:6
mean 2 3 4 7
4
or
(g`:6)2 3 4 7
4
