+`split pattern text` splits `text` around matches of the given regular expression `pattern`.
+
+This function works as if by invoking the two-argument split method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.
+
+The string "boo:and:foo", for example, yields the following results with these expressions:
