Lint/NextWithoutAccumulator is reported incorrectly for a nested loop

[leonid-shevtsov]

Expected behavior

Having a reduce loop and another loop inside of it, it's normal to next without an argument from the nested loop. It's only wrong to next without an argument from the reduce loop.

Actual behavior

Lint/NextWithoutAccumulator is reported.

Steps to reproduce the problem

Example code to reproduce:

result = [[1, 2, 3], [4, 5, 6]].inject([]) do |acc, elems|
  elems.each_with_index do |elem, i|
    next if i == 1
    acc << elem
  end
  acc
end

puts result

gets us
