Contract Patterns

All features follow Design by Contract:

search_solutions (a_keyword: STRING): ARRAYED_LIST [...]
    require
        valid_keyword: not a_keyword.is_empty
    do
        ...
    ensure
        result_attached: Result /= Void
    end

solutions_by_tier (a_tier: INTEGER): ARRAYED_LIST [...]
    require
        valid_tier: a_tier >= 1 and a_tier <= 4
    do
        ...
    end
