Functions
auto	set::_setFromArr (A, R)
auto	set::new (x, R, sep)
	Create a new set A set is an array with keys of unique values of the original array, and empty values A drawback of this approach is that original values are coerced into strings, so number values could be merged with strings.
auto	set::add (R, x, sep)
	Add elements to a set.
auto	set::rm (R, x)
	Remove element of a set.
auto	set::union (S1, S2, R)
	Union (∪)
auto	set::inter (S1, S2, R)
	Intersection (∩)
auto	set::diff (S1, S2, R)
	Difference (−)
auto	set::symdiff (S1, S2, R)
	Symmetric difference (⊕)
auto	set::eq (S1, S2)
	Equality (=)
auto	set::ne (S1, S2)
	Inequality (≠)
auto	set::subset (S1, S2)
auto	set::ssubset (S1, S2)
auto	set::superset (S1, S2)
auto	set::ssuperset (S1, S2)
auto	set::disjoint (S1, S2)
	Are disjoint (⊥)
auto	set::inside (x, S)
	Is element of (∈)
