Is there a way to compile diet templates that contain no actual dynamic

terse diet format. Maybe there's an external tool that does this?

Would be cool to have a runtime diet parser that does this and just
errors when finding dynamic data.

I did this ugly workaround, which is only tested with the diet template below:

1. Create a Dub project with diet-ng as a dependency.
2. Create a new file called src/html.d with this content: https://raw.githubusercontent.com/rejectedsoftware/diet-ng/master/source/diet/html.d
3. Do the following change:

1. Add the following code to src/app.d:

import std.stdio;

import diet.parser;
import diet.dom;
import html;

void main()
{
    auto diet = "
doctype html
html
    head
        title D statement test
    body
        this is the body
";
    auto doc = parseDiet(diet);
    auto content = doc.getHTMLMixin();

	writeln(content);
}

To me it seems it would be fairly simple to make a few changes to diet-ng to have this working out of the box.
