Is it possible to have nested templates in Go using the standard library?

How do I get nested templates like Jinja has in the python runtime. TBC what I mean is how do I have a bunch of templates inherit from a base templates, just filing in blocks of the base templates, like Jinja/django-templates does. Is it possible using just html/template in the standard library.

If that is not a possibility, what are my alternatives. Mustache seems to be an option but would I then be missing out on those nice subtle features of html/template like the context sensitive escaping etc.? What other alternatives are ther?

Thanks for reading.

having worked with other template packages, now a days I mostly work with standard html/template package, I guess I was naive to not appreciate the simplicity it provides and other goodies. I use a very similar approach to accepted answer with following changes

you don't need to wrap your layouts with additional base template, a template block is created for every parsed file so in this case it is redundant, I also like to use the block action provided in new version of go, which allows you to have default block content in case you don't provide one in child templates

// base.html
<head>{{block "head" .}} Default Title {{end}}</head>
<body>{{block "body" .}} default body {{end}}</body>

and you page templates can be the same as

// Content of index.html:
{{define "head"}}<title>index</title>{{end}}
{{define "body"}}index{{end}}

// Content of other.html:
{{define "head"}}<title>other</title>{{end}}
{{define "body"}}other{{end}}

now to execute the templates you need to call it like so 

tmpl["index.html"].ExecuteTemplate(os.Stdout, "base.html", data)
