 // StrSplit()
 //
-// Splits a given string based on the provided `Delimiter` object, returning the
-// elements within the type specified by the caller. Optionally, you may pass a
-// `Predicate` to `StrSplit()` indicating whether to include or exclude the

-// Delimiters and Predicates above.)
+// Splits a string into a sequence of substrings identified by `Delimiter`. The
+// input is processed sequentially from beginning to end, and each resulting
+// substring is filtered by an optional `Predicate` before inclusion in the
+// result set. `StrSplit()` returns a lazy range that preserves the substrings
+// original order and is convertible to the collection type specified by the
+// caller.
