@ -32,6 +32,11 @@ Interfaces are denoted by their own keyword:
Contracts can inherit interfaces as they would inherit other contracts.
All functions declared in interfaces are implicitly ``virtual``, which means that
they can be overridden. This does not automatically mean that an overriding function
can be overridden again - this is only possible if the overriding
function is marked ``virtual``.
Types defined inside interfaces and other contract-like structures
can be accessed from other contracts: ``Token.TokenType`` or ``Token.Coin``.
