Naive Caching Approach#

JavaScript only has one kind of callable object, functions, and already has very flexible field access semantics. Orc fields are implemented directly as JavaScript fields. Orc calls are supported by a runtime function prepareCallable which takes an object and adds a method orcCall(handle, args...). orcCall invokes the function in an Orc context (handling possible blocking and the like). Native Orc sites can set this.orcCall = this.

prepareCallable can no-op on all objects it has already been called on. It can also be extended to handle any kind of JavaScript object that should appear callable to Orc programs.

Note: Unlike the JavaScript API this does not allow multiple dispatch at external site calls. This matches the semantics of JavaScript in which the sites will be implemented.
