False Positive on Lint/LiteralAssignmentInCondition

[ccutrer]

Expected behavior

Lint/LiteralAssignmentInCondition should not register for non-literals

Actual behavior

A string with interpolation in the condition of a loop where the interpolation values change inside is triggering the cop.

Steps to reproduce the problem

# frozen_string_literal: true

def my_method
  until block.call(new_name = "#{dir}#{basename}-#{addition}#{extname}")
    addition += 1
    return random_backup_name if addition >= 8
  end
  new_name
end
