// The syntax-only level of support for generic methods is included in the
// 1.50 milestone for Dart. It is not experimental, but also not permanent:
// a full implementation is expected in the future. Hence, the
// 'GENERIC_METHODS' comments which were added when this feature was
// experimental have been preserved, such that it will be easy to find the
// relevant locations to update when generic methods are implemented fully.
//
// The option is still accepted, but it has no effect: The feature is enabled
// by default and it cannot be disabled.
//
// The approach taken in the implementation is to parse generic methods,
// introduce AST nodes for them, generate corresponding types (such that
// front end treatment is consistent with the code that programmers wrote),
// but considering all method type variables to have bound `dynamic` no
// matter which bound they have syntactically (such that their value as types
// is unchecked), and then replacing method type variables by a `DynamicType`
// (such that the backend does not need to take method type arguments into
// account).
//
// The feature has an informal specification which is available at
// https://gist.github.com/eernstg/4353d7b4f669745bed3a5423e04a453c.
