Passing data between Promise callbacks
In Promise-based code, there are usually many callbacks, each one having a separate scope for variables. What if you want to share data between those callbacks? This blog post describes techniques for doing so. The problem # The following code illustrates a common problem with Promise callbacks: The variable connection (line A) exists in one scope, but needs to be accessed in other scopes (line B

This addresses #862 by ensuring that repeated calls to ModuleDeclarationInstantiation() and ModuleEvaluation(), for Source Text Module Records, rethrow any exceptions they previously threw, instead of silently succeeding. This allows host environments to do top-down instantiation/evaluation of module graphs, instead of having to do bottom-up instantiation/evaluation in order to record individual f
