The availability of this feature has some r So in a sense, in some or most cases, it would indeed be cleaner to "store" the definition of a class of pages referred to in complex pagespecs as a separate object. And the most natural representation for this definition of a class of pages (adhering to the principle of wiki that what you mean is entered/stored in its most natural representation, not through some hidden disconnected code) is making a page with an inline/map/or the like, so that at the same time you store the definition and you see what it is (the set of pages is displayed to you). I would actually use it in my current "project" in ikiwiki: I actually edit a set of materials as a set of subpages `new_stuff/*`, and I also want to have a combined view of all of them (made through inline), and at another page, I want to list what has been linked to in `new_stuff/*` and what hasn't been linked to.--Ivan Z. + +> I see where you're coming from, but let's think about +> immplementation efficiency for a second. +> +> In order for inline inheritlinks=yes to work, +> the inline directive would need to be processed +> during the scan pass. +> +> When the directive was processed there, it would need +> to determine which pages get inlined (itself a moderatly +> expensive operation), and then determine which pages +> each of them link to.
