Add more tags, sanitize existing

I would suggest adding a few tags from EJS:

<%= Outputs the value into the template (HTML escaped)
<%- Outputs the unescaped value into the template
<%# Comment tag, no execution, no output
%> Plain ending tag
-%> Trim-mode ('newline slurp') tag, trims following newline

The raw print block already exists as <%==, but I'd consider changing this to EJS syntax.

I'd also do something with <%% and %%>, changing the closing tag just to %>? With the addition of -%> (see above), we can get rid of some extra whitespaces because of <%% and <%! definitions.

Support includes on compile time

I'm splitting up a project into many files, like this:

./partials/head.ejs
./partials/header.ejs
./partials/foot.ejs
./partials/footer.ejs
./index.ejs
./content/setup.ejs
./content/login.ejs
./content/error.ejs

Using them with available functions is a bit of a hassle as I have to take care of a few horrible things to make this usable. For example, my index.ejs looks something like this:

<%%
import (
        "app/common"
        "app/web/templates/partials"
        "app/web/templates/content"
        "github.com/codegangsta/inject"
)
%%><%! injector inject.Injector, view common.View %><%

        injector.Invoke(partials.HeadTemplate)
        injector.Invoke(partials.HeaderTemplate)

        %><div class="container-fluid"><%

        switch {
                case view.Content == "error":
                        injector.Invoke(content.ErrorTemplate)
                        break
                case view.Content == "setup":
                        injector.Invoke(content.SetupTemplate)
                        break
                case view.Content == "login":
                        injector.Invoke(content.LoginTemplate)
                        break
        }

        %></div><%

        injector.Invoke(partials.FooterTemplate)
        injector.Invoke(partials.FootTemplate)
%>

The problems with this approach:

I have to define extra imports
I have to use injection in the template

One possible fix would be to add an option to compile everything into one golang file, so I could skip additional imports (solves 1/2 of the problem). The name generation for functions is good enough to prevent clashes.

I suggest to add an include statement, that would "copy-paste" the file contents on compile time into the main source file. From EJS:

Includes are relative to the template with the include call. For example if you have "./views/users.ejs" and "./views/user/show.ejs" you would use <%- include('user/show'); %>.
