描述

Feel free to rename this issue if it's something more specific. This started in this comment: https://github.com/facebook/prepack/issues/1285#issuecomment-354828615 and I've found a reduced test case which I'm filing here.

According to Sebastian's comment in that issue, evaluating promises should work, but I can't get even a basic program working. The simplest program throws the error described in the other issue, "all native function values should be intrinsics". Here's the program:

研究方向
Investigate the error 'all native function values should be intrinsics' when evaluating promises. Look at the linked comment in issue #1285 for context and examine the REPL test case. The issue is in the prepack serializer or intrinsic handling directory. No maintainer response or PRs exist; this is an archived repository, so self contained research is needed.
