+    Base.rest(collection[, itr_state])
+
+Generic function for taking the tail of `collection`, starting from a specific iteration
+state `itr_state`. Return a `Tuple`, if `collection` itself is a `Tuple`, a `Vector`, if
+`collection` is an `AbstractArray` and `Iterators.rest(collection[, itr_state])` otherwise.
+Can be overloaded for user-defined collection types to customize the behavior of slurping
+in assignments, like `a, b... = collection`.
+
+!!! compat "Julia 1.6"
+    `Base.rest` requires at least Julia 1.6.
+
+# Examples
+```jldoctest
+julia> a = [1 2; 3 4]
+2×2 Matrix{Int64}:
+ 1  2
+ 3  4
+
+julia> first, state = iterate(a)
+(1, 2)
+
+julia> first, Base.rest(a, state)
+(1, [3, 2, 4])
