Merge stack traces

Tangentially related to this module, but is there any easy way to join the current stack trace (e.g. Error.captureStackTrace) with the the serialized error’s? Throwing a pre-existing error as-is may be confusing because its stack trace does not contain the current throw line’s stack.

Is the modern way to handle this via .cause?

const current = new Error('Got an error')
current.cause = deserializeError(remoteError);
throw current;

Unfortunately I think it’s not going to be well-supported for quite a while.

which don’t show it (e.g. browser console)

Hopefully, that will come sooner than later. People will start using “cause” and there will be demand.

No good way other than string handling: https://github.com/sindresorhus/got/blob/d4e34c7625c1c7000fd1b9af00e743669f83c83a/source/core/errors.ts#L55-L67

Error#cause is really the way to do this.
