Just made sense to me today as well.
#^Class
is short form for saying set the metadata for the symbol being defined (in
this case list) to the map {:tag Class}.
#^ is a reader macro for setting metadata for the compiler. That code is
simple tagging the symbol clojure/list.
(meta #'list)
will give you the map representing the metadata. :tag is used by the
compiler, but it's not clear to me in what cases...
