Thanks, I hadn't realised that using `args` would give me a list in a list.
I now just pass the list as-is (and called `rest` to avoid confusion!).

 
This used to confuse me totally.  Now I understand (I think) that
args and {*} are inverses of each other.  If you can get your head
around this, then you got it :)

If you understand what 'xargs' does on a Unix CLI, {*} is essentially a
"Tcl xargs".

It (when used for calling a proc) converts "a list of things" into
"individual parameters to the proc".

What it really does is "unwraps" the lists contents.  So instead of
having "one list containing 5 things" you end up with the internal "5
things" each individually.
