MattCoder:
Maybe It's just me, but on the example above I don't see too
much improvement:
1 word off ("return"), and "=>" instead of brackets.
In D:
Point move(in int dx, in int dy) pure nothrow {
return Point(X + dx, Y + dy);
}
Point move(in int dx, in int dy) pure nothrow => Point(X + dx, Y
+ dy);
It saves you almost 10% of typing, and makes more visible that
move is an expression. If you use UFCS chains a lot, many
functions become small and they sometimes contain just an
expression.
Currently in D you can write:
enum move = (in int dx, in int dy) pure nothrow => Point(X + dx,
Y + dy);
But here you can't specify the return value, this sometimes is a
problem, because you miss the implicit cast at the return point
(char[] -> string in pure functions, char -> dchar, Point ->
const(Point), etc).
