Bug 287079 – [JSC] Use C++ concepts to constrain `Delegate` type parameter for `Yarr::parse()`

• Status: RESOLVED
• Resolution: FIXED
• Component: JavaScriptCore

[Tetsuharu Ohzeki [UTC+9]]

`Yarr::parse()` has `Delegate` typeparameter but its constraint is documented as a comment in our code, not like an abstract class.

We can use a concepts for its constraint, I think.
