[SerSamgy (Semyon Gaivoronskiy)]

There is a complete example code in OptionParser documentation (http://ruby-doc.org/stdlib-2.3.0/libdoc/optparse/rdoc/OptionParser.html). Trying to run it got next error message:
example.rb:33:in 'parse': undefined local variable or method 'option_parser' for OptparseExample:Class (NameError) from example.rb:138:in '<main>'

I fixed a code of that example and attached it to this ticket. Maybe it should be moderated.

• Backport changed from 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN to 2.1: DONTNEED, 2.2: DONTNEED, 2.3: REQUIRED

Thank you.

I think that OptparseExample.parse should be an instance method but not a class method.
