You're focusing on the wrong apple, the Smalltalk example was 
related to ranges outside of the functional programmig family.

So can focus instead on Lisp as one possible example, use macros 
for the 50% at compile time, leave the rest of the code using 
streams for the ranges part of the equation.

If you don't like parentheses, that is also possible in Dylan or 
Template Haskell.

D hasn't invented anything newer here, and regardless of the 
wishfull thinking that it did, you won't find any references to D 
as inspiration to those features in modern languages papers like 
HOPL, rather to those that have preceeded it.
