Failed to parse file, transformation error

[WoZ]

Hello!

I'm running code on node v10.10, with istanbul 0.4.5 and node-coveralls 3.0.2.

I use standard command:

$ NODE_ENV=test istanbul cover ./node_modules/mocha/bin/_mocha --report lcovonly -- --opts tests/mocha.opts -R spec ./tests && cat ./coverage/lcov.info | ./node_modules/coveralls/bin/coveralls.js && rm -rf ./coverage

coveralls fails on file consul-kv-monitor/src/ConsulKvMonitor.js with error

Failed to parse file: /Volumes/phpstorm_volume/PhpstormProjects/consul-kv-monitor/src/ConsulKvMonitor.js
Transformation error; return original code

Here is line 320 right from the repo:

Found solution by myself. https://github.com/gotwarlost/istanbul/issues/904

Maybe it's a good idea to specify that istanbul doesn't work with es6 right in the node-coveralls readme? If so, I can prepare PR.
