o:RDoc::Markup::Verbatim;[I" * New syntax and semantics
;TI". o Block arguments are always local
;TI"/ o New semantics for block arguments
;TI"* o defined? and local variables
;TI"F o Parser expects that your source code has only valid byte
;TI"F sequence in some character encoding. Use magic comments
;TI"8 to tell the parser which encoding you use.
;TI"D o New semantics for constant definition in instance_eval
;TI" or in module_eval.
;TI"
;TI"* Deprecated syntax
;TI"J o colon (:) instead of "then" in if/unless or case expression.
;TI"- o retry in a loop or an iterator.

;[I" builtin classes and objects;T@
o;;[�I"* Kernel and Object
;TI"E o Kernel#methods and #singleton_methods used to return an

;TI"* Class and Module
;TI"A o Module#attr works as Module#attr_reader by default.
;TI"4 Optional boolean argument is obsolete.
;TI"D o Module#instance_methods, #private_instance_methods and

;TI"
;TI"* Exceptions
;TI"B o Exceptions are equal to each other if they belong to
;TI"E the same class and have the same message and backtrace.
