    So you're saying to ensure that stage_map's keys are initially lower-case to
    begin with? Well, I can't do this either since the case of the keys is
    actually valuable later on. It's only for the purposes of this specific
    comparison operation that the case should be ignored.
    Then store the string in its original case in the value part of the
    key-value pair:

    stage_map[key.lower()] = (key,whatever)
