This is called universal function call syntax (UFCS) in D. The
idea is simple: You can pull the first argument out as if the
function is a member function of that argument. So, in your
case it already works because there is already a min() function
that works with two (actually, many) parameters:
import std.algorithm;
void main() {
assert(min(3, 5) == 3);
assert(3.min(5) == 3);
}
However, many people don't like overusing it; it works well
only in cases where the first parameter is arguably the "main
character" in the operation. For example, min doesn't look good
because all parameters have equal roles in that function.

Thanks for your reply to my question.
Your book: programming in D is real a great help learning D. I
will appreciate it if your can expand the book to advance use of
D. That is, dealing with D advance use Case. I discover that the
D language is very advance but I am lock in the elementary yet
don't know the way out. This is because D is the most Higher
programming language that I ever use. Better still you can direct
me to more materials about D. I am already familiar will all D
books.
thanks
