Issue 1:
I want to access the used/generated babel configuration. Especially which presets includes which plugins exactly.

PS: I get option-manager work, the ONLY problem is that plugins which presets uses, are anonymous functions. Normally the key prop reference to the full path. Plugins included by presets have a dynamical incrementef name something with "$"

How this ensures to avoid duplication plugins?

Is there any way to get some hints of those kind of plugins, so i can list it in a kind debug output?

Issue 2:
I'm trying to use mocha with "@babel/register" but I'm getting this error:

(function (exports, require, module, __filename, __dirname) { import "core-js/modules/es6.array.iterator";
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: Unexpected string
at new Script (vm.js:74:7)
at createScript (vm.js:246:10)
at Object.runInThisContext (vm.js:298:10)
at Module._compile (internal/modules/cjs/loader.js:657:28)

This is my current configuration (babel/core and babel/register have the same version, so I don't understand what I'm doing wrong):
