 The list of requirements for valid combinations of modifiers stated for a class method is extended, as follows:
 
--  A static declaration that is not extern or abstract shall have a *block* as a *method_body*.
--  A virtual declaration that is not extern shall have a *block* as a *method_body*.
--  A private declaration that is not extern shall have a *block* as a *method_body*.
--  A sealed declaration that is not extern shall have a *block* as a *method_body*.
--  An async declaration shall have a *block* as a *method_body*.

 All formal parameter types of an interface method shall be input-safe ([§17.2.3.2](interfaces.md#17232-variance-safety)), and the return type shall be either `void` or output-safe. In addition, any output or reference formal parameter types shall also be output-safe.

 A virtual method with implementation declared in an interface may be overridden to be abstract in a derived interface. This is known as ***reabstraction***.
