Very different approach, thanks for posting.

I think your list of the *problems* of the bullet approach puts the nail in 
that coffin quite convincingly.  For example, in a world with proportional 
fonts, it doesn't make sense to create a notation that's impractical to use 
with them.

Also, A-expressions don't look all that usable at this early stage of maturity, 
and more importantly, it's not clear to me that people would easily grok their 
meaning (are they "readable"?).  Granted, people can learn anything if they 
must, but I'd like for the resulting code to have an "obvious meaning" if 
well-formatted.  But that doesn't mean that the notation can't be improved, or 
that we can't learn from them.

It'd be nice to see some examples of longer/useful functions written in this 
different notation, or whatever notation you come up with.  I created a long 
list of functions, from many different Lisp notations, when creating 
sweet-expressions to make sure that it would have good results in typical use.  
Also, please make them easy to read on a mail reader that strips initial 

To be honest, I'm really *happy* and *excited* about sweet-expressions as 
currently defined in the latest BNF.  But if there's a better alternative, now 
would be the time to raise it.
