support browser environment

hi，i found some node_modules use @wry, and when i use these modules in browser environment, i can't transform some ES6 apis elegant，would you mind support it using some babel plugins in your modules, or you can tell me how to fix the problem, thanks!

The issue names no files, tests, or entry points. Start by locating the @wry packages and their browser build or transformation setup, then determine which ES6 APIs fail in a browser environment. Done means the affected modules work in the reported browser use case with an agreed Babel-based approach.
