Not sure whether this meets your understanding of "interesting"; this
is from basic algebra:
NB. Factoring the difference of two squares (binomial)
NB, a^2 - b^2= (a+b)*(a-b)
NB. explicit version
bine=. 13 : '(x+y)*(x-y)'
2 bine 3
_5
NB. compiler suggestion of tacit version
bine

|+|*|-|

NB. tacit definition, three dyadic verbs in a row (dyadic fork)
bint=. + * -
2 bint 3
_5
NB. tree representation
5!:4 <'bint'

I am also trying to avoid hooks at this pioint.
Can you provide an interesting verb that has three dyadic verbs in a sequence.
Actually I'm trying to stranslate back and forth between explicit and tacit.
