It would be convenient if scheme-mode had the same indentation rules and
font face for `lambda' and the Greek letter `λ'.
I.e., we want this:
(lambda (x)
(* x x))
and this:
(λ (x)
(* x x))
Instead of this:
(λ (x)
(* x x))
Popular Schemes has had λ support for some time now:
* Racket supports λ (since March 2005)
* Guile supports λ (since February 2011)
* Geiser has a key binding for inserting λ (since February 2013)

I check drracket and the default indentation is as the above. I think we
should teach emacs to do it too.

Can we do this for syntax highlighting as well?
