I see. The ide is that the initial token is HASH-SYMBOL and the close 
token is
just the reverse.....

Since there are precedences in Common Lisp and PLT scheme, not to 
mention the
/* ... */ for Java or the case ... esac of Ada, I think it makes sense.

I'll work on changing the syntax, before anyone has become too heavily 
invested in it....

I've already used this syntax in my class (but I noticed that I 
frequently wrote ]# instead of #] ...
maybe its a sign....).
