For a long time I've injected the hook ([ echo) into sentences for
debugging. It seems that a trailing adverb &:([ 'description'"_) can
describe a tacit verb without affecting its behavior, or have I
overlooked something?
u&:([ 'how to use u'"_)
Dyad=: [: :
add=: +&:([ 'x add y yields the sum x + y'"_) Dyad
1 add i.4
1 2 3 4
add
[: :(+&:([ 'x add y yields the sum x + y'"_))
