Description

Is there a way (currently) to build a dynamic route at runtime out of static routes? I'm imagining a simple use case where you want to serve the same API with different URL roots, say /production/api/... and /test/api. You could parameterize your server on top-level path and server the API from there. But I can't think of a way to dynamically build a route.

Contributor guide

Research direction
Investigate Servant's type level API composition and explore if type families or existing combinators allow runtime parameterization of route prefixes. Check documentation and discussions for patterns like 'serveWithRoute' or custom combinators.
