10:09 PM Bug #14733: Error on reading log4r

03:55 PM Bug #14733: Error on reading log4r
- The error says missing log4r.

If it is just a gem missing, "gem install log4r" should work.

XPath 1.0. But it will be acceptable for users.
We can enable it by specifying "strict: true" to

10:19 PM Feature #14701: If the object is not frozen, I want to be able to redefine the compound assignment operator.
- Alternative idea: If Ruby has a feature like:
~~~ ruby
x = x.left_variable? # => true
y = x.left_variable? # => false
~~~
then inplace operation is possible without redefinition of `+=`.
