Thanks Walter, that's a great example and I like that, because parens are optional, it could also be written as

    e.d.c(3).b.a

which is even cleaner.

For those who are thinking UFCS is a trivial detail, consider that the shell and some other languages have pipe operators (|>) to make the code flow intuitively the same way as the data.

In my opinion, in a C-like language, managing to squeeze so much functionality out of the '.' operator without any downsides is the mark of a well thought out, elegant language.

Thank you for creating D.
