I see.  I had made a short .vilerc from the example, and run

        vile -D @foo.rc

to see what the trace showed (looked normal).  The typo doesn't show up
(which is probably something I should improve, at least to show an
error in the evaluation).

Also it's immediately visible with syntax highlighting turned on ;-)

no, it's not a waste.  In the last patch I had a to-do which I didn't
explore enough (how to report cases where the symbol lookup is ambiguous).
I'm adding these details to my to-do list.
