For example, {include 'path/to/template.tpl'}
?
There's no mention in the documentation of said format, but it seems to work identically to:
{include file='path/to/template.tpl'}
Is this a quirk, or by design? I prefer the tidier syntax for when I'm not passing additional vars, but want to be sure it's an accepted format (ver. 3.0.7).
