Comment 6 for bug 1243827

Did double underscores really ever work? I tried to reproduce this workaround but can't get it working.

Wrapping the strings in question in quotation marks should work though.

Also, the root cause of the problem seems to be a bug in the function resolve() in the goyaml package, which removes _all_ underscores from a string if it starts with a digit or a '+' or '-'. (see the linked branch)
