Looks good to me, thanks.

Could we have this merged and published?

Why fancylog.info() instead of fancylog.error() for stderr?

[demurgos]

This PR performs a simple replacement without changing any feature (fancyLog.info is the closest to gutil.log if you want to capture log calls with your tests). If you wish to change the behavior of your library feel free to do it.

We do our best to help maintainers to migrate (@TheDancingCode opened tons of PRs) but we focus on minimizing changes because this is already very time consuming. We still need to deal with failing CI or mistakes so we prefer to defer feature changes to maintainers.

Still, your request makes sense. You could merge the PR and then push your change, or wait for @TheDancingCode to fix it, or just pull/push changes on his branch (I believe you have write access).
