Exactly. A nicer solution for an interactive syntax would be to have,
perhaps, "globbing brackets":
mv {*.txt} /tmp
IE, we escape /into/ the special behaviour, rather than /out/ of it.
The interactive parser should easily be able to expand that to:
(run (mv ,@(glob "*.txt") /tmp))
with simple rules and nice things like that.
