+# This function is an hack because we are not enabling Puppet parser
+# that would allow us to manipulate data iterations directly in manifests.
+#
+# Example:
+# keystone_vips = ['192.168.0.1:5000', '192.168.0.2:5000']
+# $keystone_bind_opts = ['transparent']
+#
+# Using this function:
+# $keystone_vips_hash = list_to_hash($keystone_vips, $keystone_bind_opts)
+#
+# Would return:
+# $keystone_vips_hash = {
+#   '192.168.0.1:5000' => ['transparent'],
+#   '192.168.0.2:5000' => ['transparent'],
+# }
+#
+# Disclaimer: this function is an hack and will disappear once TripleO enable
+# Puppet parser.
