sort_list_of_tuple(List) -> [tuple()] when is_subtype(List,[tuple()]).

deduplicate(List) -> [any()] when is_subtype(List,[any()]).

list2binary_ex([any()]) -> binary().

is_simple_list(maybe_improper_list()) -> boolean().

is_string(maybe_improper_list()) -> boolean().

data_to_html(Data) -> binary() when is_subtype(Data,term()).
