 ### Iterator Support:
 
+Fluent iterators:
+```
+next        - return an optional value and advance by stride
+window      - return a slice and advance by stride
+filter      - acquire a unary predicate or a tuple of unary predicates
+map         - acquire a unary transform or a tuple of unary transforms
+write       - loop and write remaining iterator values to buffer
+reduce      - accumulate the range using a binary function and initial value
+strided     - set iterator stride (default 1)
+    
+```
+Standard Iterators:
+
 ```
-filter      - only return elements where predicate is true
 split       - splits a sequence on a given delimiter
 tokenize    - tokenizes a sequence on a given delimiter  
-window      - chunks a sequence in a given window size
 ```
