My understanding is that node-gulp-babel v8 should be used with

Same goes for node-babel-loader, you need v8 for babel7, but we only
have node-babel-loader 7 in Debian.
If we want babel6 to co-exist with babel7, then we don't want to just
update node-gulp-babel and node-babel-loader to v8.
We want to keep node-gulp-babel and node-babel-loader at v7 for
compatibility with babel6, and upload new node-gulp-babel8 and
node-babel-loader8 for babel7.
Back to the topic of this bug, do we really want to upgrade the yarn
build system from babel6 to babel7 ?
Here is some indication that upstream is not interested:
https://github.com/yarnpkg/yarn/pull/6322
But I have raised the issue anyway:
https://github.com/yarnpkg/yarn/issues/8083
I was able to build part of node-yarnpkg with babel7 (the part that
uses gulp-babel). Since babel 7 does not need babel-loader 8.x right
now (gulp-babel and rollup-plugin-babel are build dependencies of babel
7 and has to go together to unstable) we could continue using
babel-loader 7.x that works with babel 6 (so node-yarnpkg will be using
both babel 7 and babel 6). babel-loader 7 -> 8 transition will need to
be handled later.
I have pushed my changes to babel7 branch and the error I get is,
