like registerAs, if there has includeAs(or other name)

registerAs('a',()=>{
  return {a:'a'}
})

registerAs('b',()=>{
  return {a:includeAs('a') , b:'b'}
})

// config.get('b.a') // 'a'

Current behavior

config define separately

Expected behavior

include from other config

for example, there are 3 configs A,B and C. but B and C have the same part like A

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?

Config factories are simple JS functions that can be grouped/combined as usual. There are no plans to unnecessarily overcomplicate this package with the custom syntax.
