I think it is cool. You get lisp like power without all the parens. 
Problem is you can't parse it statically.

  It is interesting that the discussion here has veered onto these 
topics because I've been toying with implementing a language that 
interprets like Rebol, executes like Icon and has first class scopes. 
I'm not interested in speed or optimization at all, just power of 

The Rebol-like interpretation does cause some trouble for Icon-like 
control flow, because if an expression fails you might not know how the 
rest of the program would have been parsed had it not failed. But there 
seems to be a simple way around this by using brackets.
