Unconventional 'for' loop

Reports usages of for loops. It is preferable to use .each over for loops.

Example:

# Bad practice
for i in 0..5
  puts "Value is #{i}"
end

A quick-fix is available to convert a for loop into an .each loop. After the quick-fix is applied, the result looks like this:

# Good practice
(0..5).each do |i|
  puts "Value is #{i}"
end
