I'm curious: would do you say that? All evergreen browsers already include
a `stack` property on their core `Error` prototypes, so it seems to me that
the only thing preventing us from getting that useful information for
unhandled errors is the fact that `window.onerror` does not provide us with
a real Error object instances (or even fake ones with shell properties in
the case of cross-domain errors).
If I'm mistaken, please clarify. Thanks!
