  Lately I've seen on HN a few attempts to add runtime type checking to JavaScript. I'm happy with that, as in my experience adding a bunch of asserts in strategic places can really speed up prototyping and development, you become more confident, and chances are that you can catch bugs earlier. In the same vein I wrote a library that adds runtime type checking based on type combinators [1], check it out, we can share some ideas.

  It would be nice if there were a drop-in, pass-through replacement for Taxa to use in production environments. It might even just be a configuration flag: t(true) or t(false), for example.

  That way, while debugging, I could use Taxa's type-checking. Then by changing one line or setting the flag differently, I could disable it in production.
