I've been using Go's html/template for the last couple of months and all I can say is that it's still very much a toy. It's fine for basic loops and conditionals but anything beyond that is extremely limited and having proper reusable components is a constant fight against limitations, specifically because of the lack of being able to pass multiple arguments to a template. I wish the Go team had gone with something more akin to PugJS[1], which in contrast is very rich in features, flexible and dare I say fun to build components and pages with.
