+    Generate pairs of elements from an iterable.
+
+    This function uses the `tee` function from the `itertools` module to
+    create two independent iterators (`a` and `b`) from the input
+    iterable. The `next` function is used to offset the `b` iterator by
+    one index, and then the two iterators are zipped together to create
+    pairs of elements. This implementation should work with any iterable
+    in Python.
