MethodDeclaration class abstract final

A method declaration.

methodDeclaration ::= methodSignature FunctionBody

methodSignature ::= 'external'? ('abstract' | 'static')? Type? ('get' | 'set')? methodName TypeParameterList FormalParameterList

methodName ::= SimpleIdentifier | 'operator' SimpleIdentifier

Prior to the 'extension-methods' experiment, these nodes were always children of a class declaration. When the experiment is enabled, these nodes can also be children of an extension declaration.
