On the other hand, a more correct solution would be to preserve the FAKE
flag and put GV (at least flags, name and stash) on savestack. That
would allow coercing of localized fake hashes and upgrade them back on
context leaves, but would not be as simple as this.

Should I attempt to prepare a patch that does that instead?
