PATCH: before 1.0.0, a new feature increases PATCH. The new exports change nothing that exists.

New features

  • A ladder of steps for each language (D116). A language declares its steps, from the lowest to the highest, and the step of each construct as data with stepLadder. stepOf gives the lowest step that a document needs, with the first node that needs it. checkStep refuses a document above the highest step that the host accepts, and the refusal names the needed step. The new exports are StepKey, StepLadder, StepNeed, StepReason, StepRefusal, StepWalk, checkStep, isStep, stepLadder, stepOf and stepRank.
