-= Miscellaneous Syntax
-
-== Ending an Expression
-
-Ruby uses a newline as the end of an expression.  When ending a line with an
-operator, open parentheses, comma, etc. the expression will continue.
-
-You can end an expression with a <code>;</code> (semicolon).  Semicolons are
-most frequently used with <code>ruby -e</code>.
-
-== Indentation
-
-Ruby does not require any indentation.  Typically ruby programs are indented
-two spaces.
-
-If you run ruby with warnings enabled and have an indentation mis-match you
-will receive a warning.
-
-== +alias+
-
-The +alias+ keyword is most frequently used to alias methods.  When aliasing a
-method you can use either its name or a symbol:
-
-  alias new_name old_name
-  alias :new_name :old_name
-
-For methods, Module#alias_method can often be used instead of +alias+.
-
-You can also use +alias+ to alias global variables:
-
-  $old = 0
-
-  alias $new $old
-
-  p $new # prints 0
-
-You may use +alias+ in any scope.
-
-== +undef+
-
-The +undef+ keyword prevents the current class from responding to calls to the
-named methods.
-
-  undef my_method
-
-You may use symbols instead of method names:
-
-  undef :my_method
-
-You may undef multiple methods:
-
-  undef method1, method2
-
-You may use +undef+ in any scope.  See also Module#undef_method
-
-== +defined?+
-
-+defined?+ is a keyword that returns a string describing its argument:
-
-  p defined?(UNDEFINED_CONSTANT) # prints nil
-  p defined?(RUBY_VERSION)       # prints "constant"
-  p defined?(1 + 1)              # prints "method"
-
-You don't need to use parenthesis with +defined?+ but they are recommended due
-to the {low precedence}[rdoc-ref:syntax/precedence.rdoc] of +defined?+.
-
-For example, if you wish to check if an instance variable exists and that the
-instance variable is zero:
-
-  defined? @instance_variable && @instance_variable.zero?
-
-This returns <code>"expression"</code> which is not what you want if the
-instance variable is not defined.
-
-  @instance_variable = 1
-  defined?(@instance_variable) && @instance_variable.zero?
-
-Adding parentheses when checking if the instance variable is defined is a
-better check.  This correctly returns +nil+ when the instance variable is not
-defined and +false+ when the instance variable is not zero.
-
-Using the specific reflection methods such as instance_variable_defined? for
-instance variables or const_defined? for constants is less error prone than
-using +defined?+.
-
-== +BEGIN+ and +END+
-
-+BEGIN+ defines a block that is run before any other code in the current file.
-It is typically used in one-liners with <code>ruby -e</code>.  Similarly +END+
-defines a block that is run after any other code.
-
-+BEGIN+ must appear at top-level and +END+ will issue a warning when you use it
-inside a method.
-
-Here is an example:
-
-  BEGIN {
-    count = 0
-  }
-
-You must use <code>{</code> and <code>}</code> you may not use +do+ and +end+.
-
-Here is an example one-liner that adds numbers from standard input or any files
-in the argument list:
-
-  ruby -ne 'BEGIN { count = 0 }; END { puts count }; count += gets.to_i'
-
