Yes I am aware of the comments argument but it is not what I was
referring to. What I want is, if I had the following in a file called
"Haskell.org" :
* Root
Root comment
#+begin_src haskell :tangle Main.hs
=A0 test =3D length
=A0 main =3D print $ test [1,2,3]
#+end_src

I would like the following output in the tangled file Main.hs:

{-# LINE 4 "Haskell.org" #-}
test =3D length
main =3D print $ test [1,2,3]

The line that starts with {-# LINE ... #-} is a pragma that tells the
compiler that this line corresponds to line 4 in Haskell.org and if
there is an error it will point to that file and not to Main.hs.

Can I take it that this functionality doesn't yet exist?
