+
+    \brief removes an element from a seq.
+
+    seq = seq from which an element is to be removed.
+    index = The zero-based position in seq of the element to be removed.
+
+    If index is greater or equal to the seq size the result is undefined.
+    If the seq is a single element and the index is 0 the result is an empty seq.
+    Otherwise the result is a seq after removing the index element.
