https://doc.arvados.org/v1.4/sdk/go/example.html has the title "Arvados | Python | Examples"

the example starts with a #<Liquid::Comment:0x0000561e37195428> that should not be there.

and compilation fails:

go build .

s/git.curoverse.com/git.arvados.org/g did make it work BTW

also golint output:
