The thing I would like to "transclude" the most is filters
So I may gave a complex or long filter to identify active tasks that are
not closed, cancelled or archived and in a particular context current
domain, project/client then transclude them
In a filter "[{active-tasks}{this-context}]
Something like this can already be done but I do not want the filters
active-tasks appearing as regular tiddlers and in search results
I could use {$:/filter/this-context} however it quickly starts to loose its
readability.
Perhaps a "name space" $:/transcludes such that $:/transcludes/this-context
can be transcluded as {this-context}
or even smarter
Perhaps a "name space" $:/transclude/filters such that
$:/$:/transclude/filters/in-context creates a filter operator
"incontext[]" that can be negated "!incontext[]" and perhaps we can use
suffix and content in some way
This would make it much easier to share filters, keep macros a lot clearer
and help new users learn from existing ones.

Tony
