No, it can't. It depend on your vim script. We want to get the result without
side effect.
---------------------------------
function! s:bar()
let a = ''
redir => a
call thirdparty#library#function()
redir END
return a
endfunction
echo s:bar()
---------------------------------
Do you know the wheather thirdparty#library#function() call redir? or not?
I don't think all of vim script like the thirdparty#library#function() call
your Redir function.
