|     +----------------+   +--------------------+ 
|     | file: atest.rb |   | file: btest.rb     |
|     +----------------+   +--------------------+
|     | puts a         |   | a = 12
|     | a = 24         |   | require 'atest.rb' |
|     | puts a         |   | puts a             |
|     +----------------+   +--------------------+

Yes, but this behavior will be changed in the future.

require/load will not copy the toplevel local variables, so that the
first reference to a in atest.rb will raise an exception.
