|% ++  term  hoon ++  term  hoon -​-Creates a core, a Hoon data structure which contains one or more computational methods (arms).

Produces a core, a cell of [battery payload].

This type of core does not automatically come with an arm buc which is computed immediately, but it can contain many other arms, declared by one of the lus runes. In our work, we'll mostly use ++ and +$.

|% takes any number of children in pairs of term (arm name) and some hoon (code to be evaluated when arm is computed).

Each pair of term and hoon is preceded by ++ or another arm marker.

|% must be closed by the boundary --
