Uses [[Template:DPLlua helper]] to make it possible to include all parameters of a template while maintaining good performance. 

{{Helper module|name=DPLlua
|fname1 = ask(&nbsp;...&nbsp;)
|ftype1 = tables
|fuse1 = <code>ask</code> takes a series of tables each containing the settings for a DPL query; it will return the same number of result tables as input tables. All formatting settings are stripped from the config. If the config does not contains <code>include</code>, the result will be a simple list of page names. 
<pre>
{
	<pagename#1>,
	<pagename#2>,
	<pagename#3>,
}
</pre>
A query with an <code>include</code> of the form <code>include = '{template#1}:1:2:param1:param2, {template#2}:3:param1, %0'</code> will give a result like
<pre>
{
	['include'] = {
		['template#1'] = {
			[1] = val#1,
			[2] = val#2,
			['param1'] = val#3,
			['param2'] = val#4,
		},
		['template#2'] = {
			[3] = val#5,
			['param1'] = val#6,
		},
		['%0'] = val#7
	},
	['title'] = <pagename>
}
</pre>
You can also do <code>include = '{some template}'</code> which will include all parameters of that template in their unexpanded form (templates are not expanded but some content in parser tags is placed in strip markers).

If the config value <code>count</code> is larger than 500 it will automatically generate multiple DPL queries with offsets and their outputs will be combined in the returned result.

The output contains a <code>time</code> field so you don't need to use <code>%DPLTIME%</code>.

If the DPL throws an error it will be available in the <code>error</code> field of the output.

Differences with normal DPL:
* All formatting options are ignored
* Surrogate templates (e.g. <code><nowiki>include = '{template|other template}'</nowiki></code> are ignored
* Using <code>include = '{template}'</code> will include all the arguments of that template instead of expanding the template
* The parameter <code>count</code> can go higher than 500
* When the value of a parameter is a table it will be expanded into multiple lines. E.g. doing <code>notcategory = {val#1, val#2}</code> will expand into 
<pre>
|notcategory = val#1
|notcategory = val#2
</pre>

Note of warning, if you include content containing <code>§</code> symbols the result may be unreliable. If you include a whole template (e.g. <code>include = '{some template}'</code>), content inside strip markers (not nowiki) can't be cleaned up inside lua so pipe characters (<code>&#124;</code>) will be replaced with <code>§</code> characters and the <code>{</code> and <code>}</code> characters are replaced by <code>&#10100;</code> (U+2774) and <code>&#10101;</code> (U+2775). Use <code>include = '{some template}, {some template}:1:2:3'</code> instead for the problem parameters.
