Interesting conceptual challenge here: is the * an operator for
targeting the main page, or is it a shorthand for the main page? I
think of it as a shorthand, whereas you clearly think of it as an
operator. I'm not sure which is more right.

This is actually connected to another problem I haven't solved yet.
I'm working on templatable attachment lists as an extension of
pagelists, which will require references to the previous, current and
next file, in the style of {=$Title}. Internally, these are realised
in PmWiki using the same code that makes stuff like {*$Title} work.
And because I'm silly, I figure that attachment variables ought to be
usable from normal pagelists as well.

...which means that your suggestion is probably better, as then in
templates you'd have {=Attach:duck.jpg$Filesize} for the current page
and something like {Attach:=$Filesize} for the current file.
