[sswaroopgupta]

Expected behavior
Should give me a warning

Actual behavior

-e: /Users/sswaroop/rubytest/step_implementations/step_implementation.rb:7: syntax error, unexpected '|', expecting keyword_end (SyntaxError)
    |@@vowels|
     ^
/Users/sswaroop/rubytest/step_implementations/step_implementation.rb:41: syntax error, unexpected end-of-input, expecting keyword_end
[ValidationError] /Users/sswaroop/rubytest/specs/example.spec:12: Connection closed [[::1]:50844] cause: EOF => 'Vowels in English language are "aeiou".'

Steps to replicate

1. Create a ruby project
2. Give the following implementation

@@vowels;

step 'Vowels in English language are <vowels>.' do |vowels|
  @@vowels = Set.new [];
  vowels.scan(/./).each do |vowel|
    @@vowels.add(vowel)
    |@@vowels|
  end
end

1. run the specs and you will see the error
