'unless' statement with 'else'

Reports unless statements used with else. It is preferable to put the positive branch first.

Example:

# Bad practice
a = 1
unless a > 2
  puts 'a is 2 or less'
else
  puts 'a is greater than 2'
end

A quick-fix is available to convert an unless into if. After the quick-fix is applied, the result looks like this:

# Good practice
a = 1
if a > 2
  puts 'a is greater than 2'
else
  puts 'a is 2 or less'
end
