sequence in some character encoding. Use magic comments
|
||||
to tell the parser which encoding you use.

o New semantics for constant definition in instance_eval
|
||||
or in module_eval.

||||
o Module#attr is an alias of attr_reader
|
||||
o Module#instance_methods, #private_instance_methods, #public_instance_methods
