data DiffResult d Source

Same | Both arguments are the same. |

SameHead d | The arguments are recursive expressions of the same form, but their subterms differ. Return a "decorated" term that shows where the differences are |

Differ d d | The arguments differ and are not of similar form (don't recurse) |
