That's great but
1) I have no idea how to type it. Can I easily and comfortably? In emacs?
2) Will it show up in PuTTY (and everyone else's terminals/IDEs)? in
everyone's mail readers (including Gmail)?
3) What encoding do my textfiles need to be in (i.e. how many bytes
per char)? How do I do that? Does Haskell even support everything
related to Unicode that we'd need?

If the answers are satisfactory to all these questions, then Unicode
is a good idea (and that's the ideal character). If not, we're sadly
stuck in ASCII land.


P.S. Plus that opens a lot of cans of worms for writing programs with
all those fancy symbols! APL here we come!
