Is there any practical way to find all the tiddlers that a tiddler is directly transcluded in?
In an ideal world, I am imagining a filter operator that would work rather like links[] or backlinks[] do, where only "hard" links that can be detected by a quick look at the wikitext count. Say, '[[SomeTiddler]transcludes[]]' would find the tiddlers that contain a reference to {{SomeTiddler}} (or perhaps {{SomeTiddler||SomeTemplate}}, or maybe with a suffix {{SomeTiddler!!SomeField}}). Attempting to propagate this search through multiple levels of transclusion would presumably be impractical, and probably not even very useful.
A transcluding[] operator that finds all tiddlers transcluded by the input would also seem to make sense.
Immediate use case: I would like to be able to transclude small bits of reference information in multiple places and then display on the reused tiddler all the locations where it's being used.
