Chunks from extract.
Escaping mode.
A function that binds params and returns the HTML.
Values are inserted without HTML escaping unless options.escape is
true; then {{name}} values go through escapeHtml and
{{{name}}} values stay raw. extract and compile are plain JavaScript,
so they also work on runtimes without a filesystem.
Compile chunks into a renderer. The template is flattened once into
statics[0] slot[0] statics[1] … slot[n-1] statics[n]; a render does one type check onparams, then one lookup per slot.
