The design of the set helper prevents it's use in a pipeline

[jhillyerd]

The set helper presently expects the following argument order: key, value, renderArgs

Because Go template pipelines use the result of the previous expression as the final argument, you can't use them with the set helper. Instead you must use an intermediate variable:

{{$title := printf "Title for %v" .name}}
{{set "title" $title .}}

If renderArgs was moved to the first argument of the set helper, it could be more concise:

{{printf "Title for %v" .name | set . "title"}}

I'm still learning Go, Revel and templates, so my apologies if I am incorrect.

EDIT: It would also make sense to make the same change to append

Will send a note to revel-framework google group.

Let me know if you guys end up making anything with it!
