-# split($string, $delimiter) : $string
-# split($string[], $delimiter) : $string[][]
+# This function has two modes of operation:
#
-# Split the first argument(s) on every $delimiter. $delimiter is interpreted as
+# split($string, $delimiter) : $string
+#
+# Split the first argument on every $delimiter. $delimiter is interpreted as
# Ruby regular expression.
#
+# split($string[], $delimiter) : $string[][]
+#
+# Returns an array of split results with the result of applying split to each
+# item from the first argument.
+#
# For long-term portability it is recommended to refrain from using Ruby's
# extended RE features.
