A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
In older versions of Ruby, bare ranges could be used as conditions in if, while, and similar statements. You could, for example, have written the previous code fragment as:
print if /start/../end/
This is no longer supported. Unfortunately, no error is raised; the test will simply succeed each time.
