%- Evalutes a gate

%- takes two children:

  • The first child is a wing resolution which evalutes to a gate (this may be a gate from the standard library.)
  • The second child is some hoon, which will be used as the gate's sample.

It is quite common to see %- in its irregular form as (gate hoon).
