Still not sure where this is failing.

<verbatim>
% mk::loop x db.dirs!90.files { puts "$x, [mk::get $x name]" }
db.dirs!90.files!0, cross.png
db.dirs!90.files!1, tick.png
db.dirs!90.files!2, tclp.gif
% mk::view info db.dirs!90.files
name size:I date:I contents:B
% mk::get db.dirs!90.files!0 size
655
% string length [mk::get db.dirs!90.files!0 contents]
655
% mk::get db.dirs!90.files!0 -size contents
655
