[racket] Re-usable C-like input syntax

Anyone know where Honu disappeared to?  I don't see it in the current 
manual, nor in PLaneT.

BTW, the usual pattern is that someone will think Racket/Scheme/Lisp 
needs a C-like syntax, but after they actually start using parens for 
idiomatic programming, they see the advantages.  However, EE embedded 
systems programmers are a special case, :) and I would give them their 
curly braces.
