Try typing "cmake --help-command function" on the command line.
Especially look at ARGN...

BTW, what you are doing is passing in the *name* of a list. And the
output isn't "..11", but "..list". You could fix it by changing the
function to read

FUNCTION (MY_FUNC list)
   MESSAGE ("..${${list}}")
ENDFUNCTION ()


And "list" or "LIST" (or any other capitalization) is a built-in
function, so you shouldn't use it as a variable name.
