If I recall correctly, the original Scheme compiler (wasn't it called 
Rabbit?) contained code where '[' and ']' were used to denote 'hunks', 
which I think were kind of like small arrays used as structures.
But maybe that was a relic from the Lisp that Rabbit was written in, 
rahter than part of Scheme itself.

And there have been a number of dialects that used ']' as a kind of  
superparenthis that closes all open parentheses back to a matching '[' 
or to the start of the s-expression, whichever comes first.  That 
superficialy resembles what I was doing, but I utterly reject that, 
becaue it hides parenthesis mismatch instead of making it easier to see.
