A TC39 proposal to add a method to sum multiple values

values in the iterable using a more precise algorithm

Open questions about a feature may be a source of
future web compat or interop issues. Please list open
issues (e.g. links to known github issues in the
project for the feature specification) whose
resolution may introduce web compat/interop risk
(e.g., changing to naming or structure of the API in a
non-backward-compatible way).
