A few thoughts, probably based on misunderstanding from my side:
a) Is there anything within the $:/ name space that would *not* be a
variable? Shouldn't just "$:/" suffice?
b) ...because wasn't a main point with the shadow tid cascade analogy that
overwriting tids use the exact same title as the shadow tid? I.e that we
should not have to name the tiddlers that act as variables in any
particular way but that they instead are always treated as variables but
with a fallback to a constant value (i.e the tiddler itself... or maybe
tiddler content).
c) Are you saying there *must *exist a tiddler in order for it to be a
variable? If yes, in the case of a currentTiddler variable, maybe the
fallback physical tid would be a default tiddler? Can it not simply be a
missing tiddler? Or just a dummy tiddler. Or the way it is currently; the
historylist with a "variable field" for current... but maybe that breaks
the concept...?

Couldn't e.g {{Foo}} cover everything? - The system checks to see if Foo is
a variable, in which case you get that value. Not variable - go up the
tiddler store stack to check if there is a macro named so... get evaluated
macro. Last fallback, tidder : transclusion.
I.e only one kind of brackets and one name. System vars/macros/tids treated
the same way but always have prefix $ or similar.
...?
