bfgeek has just created a new issue for https://github.com/w3c/css-houdini-drafts: == [css-layout-api] Lifetime policy for passed in objects, e.g. LayoutChild == When the web developer gets arguments from the UA, e.g. ```js *intrinsicSizes(children, edges, styleMap) { } *layout(children, edges, constraints, styleMap) { } ``` What is the lifetime of each of the objects (the children in particular). For the `LayoutChild` if we make it have the lifetime the same as the `box` which it belongs to the web developer can do useful things like: ``` *layout(children) { const child = children[0]; const result = this.someComplexPreCalculation(child); } someComplexPreCalculation(child) { if (!child.result) { /* something */ child.result = someResult; } return result; } ``` Is there any value for doing this for the other params? (paint doesn't do this currently). Please view or discuss this issue at https://github.com/w3c/css-houdini-drafts/issues/745 using your GitHub account
