Joshua,
I think that explanation is useful.
The fact is I write most of my code with currentTiddler the target and use
set or list to alter this value as needed.
I have being using the templating mechanism to great effect, using
`{{||template}}` and relying on the context, ie currentTiddler is a common
application. I have also developed solution where the context is set eg
{{edit||$:/autotag}} will transclude all tiddlers tagged $:/autotag/edit
and {{edit||$:/autotag/actions}} will transclude all tiddlers tagged
$:/autotag/actions/edit
thus I can use actions={{edit||$:/autotag/actions}}, in these cases
$:/autotag/actions/edit and $:/autotag/edit are sophisticated template
tiddlers.
The issue is when I want to programmatically alter the "currentTiddler"
used in the transcludes. There are half a dozen methods all of which
complicate the code. eg a macro's etc...
All I am asking for is a native method to parameterise the long form, as we
can with literals in the short form.
So it we keep the transclude widget as is but permit setting the
currentTiddler in a parameter I could use the much simpler form using your
terminology
<$transclude tiddler=<<transcludedtiddler>> context=<<currentContext>>/>
However the effort to persuade anyone on this simple "improvement" has
being a little long winded.
Regards
Tony
