In release 0.17 [changelog](https://nim-lang.org/blog/2017/05/17/version-0170-released.html), it mentions
> The popular “colon block of statements” syntax is now also supported for let > and var statements and assignments: > template ve(value, effect): untyped = > effect value > let x = ve(4): > echo "welcome to Nim!" > This is particularly useful for DSLs that help in tree construction. Are there any example of real code using this feature since then?
