Metadata attaches to the form following it, so I would read this (with my
Clojure Reader hat on) as:
( read list begin
meta read symbol
#_ read and discard next form
^ read meta and form, then apply meta to form
:hello read keyword
[] read vector
... apply :hello as meta to []
... discard [] with metadata
) end list
which would yield a final form: (meta), which should throw an arity
exception. So looks correct to me.
