[the templating docs](http://docs.puppetlabs.com/guides/templating.html) for
the basic functionality.
Additionally, you can pass a hash, as the last argument, which will be turned into
local variables and available to the template itself. This will allow you to define
variables in a template and pass them down to a template you include in the current
template. An example:
scope.function_templatewlv(['sub_template', { 'local_var' => 'value' }])
Note that if multiple templates are specified, their output is all
concatenated and returned as the output of the function.") do |vals|
