I don't see the need for using '@' or '@{0}' - at least for the time
being until you introduce more 'system' variables in addition to the
chain name. If you wish to adopt '@{X}' for action parameters (instead
of, or in addition to, the current '$X' or '${X}') then that's fine,
but, for the time being at least, I don't see the need for this. My two
pence, of course.
