-# Note: from Puppet 6.0.0, the compatible function with the same name in Puppet core
-# will be used instead of this function.
+# The original size() function did not handle Puppets new type capabilities, so this function
+# is a Puppet 4 compatible solution.
+#
+# > **Note:** **Deprecated** from Puppet 6.0.0, this function has been replaced with a
+# built-in [`length`](https://puppet.com/docs/puppet/latest/function.html#length) function.
