close #142

Is it a draft as the proposal has not reached stage-4?

First, I am waiting for the release of acorn. It is implemented in the master branch.
https://github.com/acornjs/acorn/commits/master/

After that, we will need to change espree and regexpp.
A PR has been opened for regexpp, but if the source code of acorn changes before the release, we may make changes accordingly.
eslint-community/regexpp#195
