Drop-in replacement for babel-register that turns into a no-op if the running
node.js version is >= the node.js version listed in your project's .nvmrc.
This allows you to avoid transpilation in node.js versions that you deem "good enough" to support the feature set required by your project.
The rationale is described here: babel/babel#6163
I hope babel-preset-env or babel-register adopts this capability so this module won't have to exist :)
