# The bad way
def to_hash
  hash = {}
  @reports.each do |report|
    hash.merge! report.to_hash
  end
  hash
end


# An approach much better
def to_hash
  @reports.inject({}) do |report_hash, report|
    report_hash.merge report.to_hash
  end
end


# The right way
def to_hash
  @reports.map(&:to_hash).reduce({}, :merge)
end
