Discussion on: Pattern-Match your JavaScript with Z

This is incredible. I have a lot of questions regarding how this is done. I use Ramda's cond quite a bit. But I really like this syntax.

I'm curious to see how this works when minified. I believe it is using some type of reflection.

It seems to use a package called js-function-reflector which transforms a function object to it's string representation and parses it again.

and js-function-reflector uses the toString() method availaible on functions

the toString()

That doesn't seem like it would work for minified code as the parameter names would be uglified.

It works as long as you don't compile the default arguments to ES5.
