@spec at!(Enum.t(), integer()) :: any()

Like Enum.at/2 but raises if index is out of bounds.

@spec compact(Enum.t()) :: Enum.t()

Removes nil elements from enum.

@spec first!(Enum.t()) :: any()

Returns the first item of enum, or raises if it is empty.

@spec is_map_or_keyword(any()) :: boolean()

Returns true if the value is a map or a keyword list.

This cannot be used as a guard because it uses Keyword.keyword? under the hood. Also, because of that, it might scan an entire list to see if it's a keyword list, so it might be expensive.

@spec isort(Enum.t()) :: Enum.t()

Sorts enum case-insensitively. Uses Enum.sort_by/3 under the hood.

@spec isort_by(Enum.t(), (any() -> any())) :: Enum.t()

Sorts enum case-insensitively by mapper function. Uses Enum.sort_by/3 under the hood.

@spec tids(Enum.t()) :: list()

Returns :tid fields from enumerable.
