+# XXX
+# why are we passing around root like a cheap whore?                            because root is where things are (f(x) -> y)
+# looking into it, i think we should have a global config object using
+# https://metacpan.org/pod/Readonly                                             fuck read only, constants are for faggots
+#
+# i modified the routing heavily, this is how people do it;                     very scary
+# pretty clean
+# you must also realize that not all routes are necessarily templates,          then they are routed by nginx.
+# it could be a redirect for example, so the original solution would
+# complicate beyond comprehension                                               ACK.
