a => { return 2*a; } /\ \ / || \ / || \ / || \ / || \ / This is \ / function \ This is definition of delegate definition \so you have a function that returns delegate. ``` it's like a => a => 2*a; or (a){ return () { return 2*a; }
I believe that a lot of other languages work differently, so when their knowledge are transposed to D, people get confused at first.
Eg. in JS:
x = x => x * 2;
x = x =>{ return x * 2; }
//equivalent
