Although I am in favor of {{#ask:}} at the earliest possible
conveneince, after a cursory look through the code, I'm fairly certain
this extension will fail to operate as expected.
The first reason is that <ask>, which is an extension tag, will always
return fully qualified HTML. The output of a parser function is
expected to be wikitext, which will be further processed. The result
is that if the output of the {{#ask:}} call contains any links,
they'll be HTML links (like <a href="something">something</a>), not
wiki text (like [[something]]). When the Parser reads these HTML tags
during subsequent processing, it'll convert the '<' and '>' symbols to
their entity equivalents '<' and '>' so in the browser you
actually see '<a href="...">whatever</a>', not a nice link.
The second reason is that one of the huge benefits of having an
{{#ask:}} parser function is nesting. The idea that you could
{{#ask:something={{#ask:something else}}}}. I'm not sure if SMW
supports nested <ask> tags, but if not, this would also be a failure
mode of the aforementioned extension.
Again, I would like nothing more from SMW than an {{#ask:}} template -
which would be a __HUGE__ improvement for advanced use cases, but I
don't think that this extension is the answer everyone hopes it is.
