Re: Syntax, expressiveness and the beauty of Tcl

I'm not sure whether it's cleaner and less confusing.. but
experimenting shows that the dollar parser's bevavior on braces is
surprising anyway:

15 % set {hello world} 1
1
45 % set x ${{hello world}}
can't read "{hello world": no such variable
So the first brace encountered is taken for closing, independent of
nesting depth?
