+== Templated Response class ==
+
+This class cuts back on the standard calls to load the template, generate a stream and populate it with data and subsequently render it. The data parameter is best passed as a dict.
+
+{{{
+#!python
+from werkzeug import Response as BaseResponse
+
+TEMPLATES_DIR = # some path
+
+class Response(BaseResponse):
+    """Subclass of base responses that has a default mimetype of text/html."""
+    default_mimetype = "text/html"
+
+class TemplatedResponse(Response):
+    """Response class with built in template renderer."""
+
+    loader = None
+
+    def __init__(self, template, data):
+        if TemplatedResponse.loader is None:
+            TemplatedResponse.loader = TemplateLoader(TEMPLATES_DIR, auto_reload=True)
+        self.template = self.loader.load(template)
+        self.stream = self.template.generate(data=data)
+        self.response = self.stream.render('xhtml', doctype=DocType.XHTML_STRICT)
+
+        Response.__init__(self, self.response)
+}}}
+
+Within your code you can then import this class and do something like:
+
+{{{
+#!python
+return TemplatedResponse(template='my_template.html', data={'name': some_variable})
+}}}
