One very simple idea to use this (in Xemacs) would be to make an X-Symbol=
for=20
haskell (http://x-symbol.sourceforge.net/) . It doesn't seem that complic=
ated=20
but I know nothing abuot elisp at this time.
Ths mode can map tokens into math symbols and vice-versa.
We can define the tokens and the associations, one simple idea would be t=
o map=20
_alpha into alphas, =3D> into real arrows, etc.
