The "Built-in Types" section of the library documentation does not explain how two dictionaries are compared for equality. The place where this is documented is under "Comparisons" in the Language Reference: > Mappings (dictionaries) compare equal if and only if they have the same (key, value) pairs. but it is not obvious from the section on dictionaries in "Built-in Types" that this is where to look. (Contrast with the situation for sequences and sets, where "Built-in Types" does explain how these objects are compared for equality.) I suggest that the "Built-in Types" section should explain how two dictionaries are tested for equality. |

The 3.4 sequence section also has this: "Sequences of the same type also support comparisons. In particular, tuples and lists are compared lexicographically by comparing corresponding elements." I agree that dicts should have a similar sentence or two. Neither the sequence or (frozen)set sections reference the language manual, so I will leave that out. |
