Universal Function Call Syntax. C# calls them extension methods.
Basically, the ability to call a method directly on a class (in the form
of A.MyMethod) without it being declared in the class. Usually just a
static/global method that gets rewritten. Instead of MyMethod(A), you
can use A.MyMethod.

The two biggest things that I believe D would benefit from, in terms of
readability, are UFCS and C#-style lambdas (which were already discussed).
Something like
'array(find("test", select!("a.name")(filter!("a.num> 3")(Elements))))'
Could be rewritten much cleaner as
Elements.filter!"a.num> 3"
.select!"a.name"
.find("test")
.array();
The first one is very confusing, hard to split across multiple lines
without losing meaning, and difficult to see what it even operates on
(assume Elements is not an array and thus can not be used with the
current implementation of UFCS). The second one, you can clearly see
operates on Elements, you can clearly split it across multiple lines,
and it's very obvious where things stop and end. Plus, it eliminates at
least one set of parenthesis per function call, not to mention being
much easier to write as it's in order of steps instead of opposite order.
Pardon, what does UFCS stand for?
