... OK, your solution works -

- But I'd need one which doesn't force user to hook manually; i.e. without:

----
\let\Oldstoptext\stoptext
\def\stoptext{%
   \startluacode
   context("END")
   \stopluacode
   \Oldstoptext
}
----

Hooking should be performed in a Lua function and should be "invisible" to the user.

More complicated example:

---- t-Hook4.mkiv
\startluacode
   function foo()
     local stoptext_p = context.stoptext

     context.stoptext = function(...)
       context("END")
       stoptext_p(...)
     end
   end
\stopluacode

\starttext
   \input knuth

   \ctxlua{foo()} % This should cause "END" to appear at the end of the document
\stoptext
----

In this case, "foo()" is a function which does the hooking; and "foo()" may be placed in another file or Lua toolbox, so user is to call Lua's "require 'my-Lua-toolbox-with-foo' foo()".

So user is not forced to know how the function works; once he uses it, the text "END" will appear at the end of the document.

- And this doesn't happen to me; and my goal is to make it work.
