see #116

for now, I didn't add it to the GitHub CI

I would expect it to be merged and tested first

Please note, it would report a bunch of errors to be addressed:

Thanks, I typically get to these PR's on the weekend, hence the delay.

[ccoVeille]

No problems, thanks for letting me know.

[ccoVeille]

how was your weekend ? :grin:

[mfridman]

Thanks, let's give it a try. I'll fix up the errors and also move over to testify since it's so widely used (granted I wish something better came along).
