As a side effect, nominal types + can encode opaque types. We changed all opaque-handling logic and improved + opaque warnings in Dialyzer. + + All existing Erlang type systems are structural: two types are seen as + equivalent if their structures are the same. Type comparisons are based on the + structures of the types, not on how the user explicitly defines them. For + example, in the following example, `meter()` and `foot()` are equivalent. The + two types can be used interchangeably. Neither of them differ from the basic + type `integer()`. + + -type meter() :: integer(). + -type foot() :: integer(). + + Nominal typing is an alternative type system, where two types are equivalent + if and only if they are declared with the same type name. The EEP proposes one + new syntax -nominal for declaring nominal types. Under nominal typing, + `meter()` and `foot()` are no longer compatible. Whenever a function expects + type `meter()`, passing in type `foot()` would result in a Dialyzer error. + + -nominal meter() :: integer(). + -nominal foot() :: integer(). + + More nominal type-checking rules can be found in the EEP. It is worth noting + that most work for adding nominal types and type-checking is in + `erl_types.erl`.
