I was thinking about the quality of the documentation I have left
behind.

by the way, the bottom line is that I was trying to manipulate a
foreign structure (from the Xlib) getting it out of where it belongs
with this trick by the means of allocaSetWindowAttributes:

attributes <- allocaSetWindowAttributes (\s -> return $ s )

attributes resulted garbage but the compiler did not complain.

the right thing to do is to manipulate it from within the place where
it was possible for the two of you to meet:
window <- allocaSetWindowAttributes $
        \attributes -> do    
and do what ever you want to do.

I don't know if now it is clearer than before, but hopefully that
could be that case for someone searching for xlib and
overright_redirect.
hopefully.
