This is also the style we used in an in house server side library
meant to be used mainly for REST and WebSocket connections.
The routing is inspired from Python Flask and Python aiohttp  with
- the routes can be added and removed at runtime (and from other route handlers)
- we needed dynamic routes - moreover the dynamic part needed to match
multiple path segments and more "specific" route handlers needed to
take precedence over the more "generic" ones (example below)
- support for asynchronous (deferred) route handlers - to support the
cases when handling a request requires a lengthy operation.
- full access to request / response objects to offload as much logic
as possible from the core server library.
Example of specific / generic route handlers:
("POST", "/api/v1/<device_id>/operation_a/") - handles some POST requests
("POST", "<url>/") - handles all the other POST requests regardless
how many path segments (matches both "/a/" and "a/b/" and so on)
