Remove routes from URLRouter in vibe.d

[FreeSlave via Digitalmars-d-learn]

I want to be able to dynamically remove some routes in my Vibe.d 
application.
URLRouter accounts for newly added routes, but I can't find a way 
to clear routes unless I create the new URLRouter object, in 
which case I also need to re-create HTTP listener.
Also, is it safe to replace already existing route handlers?
