Chaining set accessors

Topics: Language Specification

Chapter 4.5 Object Literals describes get/set accessors. It states that a set accessor must not return anything (must have a void return type). This will disallow writing fluent APIs for chaining.

Is there any specific reason for this limitation? I'd love to see the ability to allow chaining of set accessors.

This is a limitation of the JavaScript runtime:
var x = { set n() { return 4 } };
var y;
y = x = 3; // y is 3, not 4
Out of curiosity, how would you even use this feature if it did exist?

Hi Ryan,

thanks for your answer. I actually gotta admit that I got some things mixed up here. You're right, this doesn't really make sense. I apologize!

Just got into Typescript and digging through the spec, so I guess some things still have to settle in. I really love it, though, thanks for your work!
