Need more EO-tests

You can add your .eo tests to src/test/eo/org/eolang/dejump.
Rules for tests:

• has only one outer abstract object, inside of which the logic of the test;
• name of this object should be equal to the name of file with this test:
  for example, if your test has a "main" object [] > easy_test, so the .eo file should be called easy_test.eo;
• your test should not contain any alias-es:
  for example, if you use object stdout in your code, use it as QQ.io.stdout, NOT with alias;
• logic of your test can be absolutely different - it is no requirement to has a goto object inside, but, since
  we check goto elimination, it would be better that your test will have it :) ;
• based on concept of transformations, there are cases of using goto, which are not allowed for this applications:

1. When objects forward/backward encapsulated (directly or throw other objects) in any foreign objects -- objects, that
   are implemented somewhere in your code (objects, that general EO-syntax doesn't support):

goto
  [g]
    foreign_obj > @
      QQ.io.stdout
        "We don't know the logic\n"
      g.forward TRUE

2. Cases, where we dataize objects forward/backward outside object goto:

goto
  [g]
    seq > @
      foo g
[x] > foo
  x.forward 25

As examples of tests, check .eo files at src/test/eo/org/eolang/dejump.
