I know I've seen such code in the past, but it's been a while, and I
can't remember exactly where it was.

Let me put this another way: take a look at the Semantic Versioning
Specification. [1][2] An increment to the patch version is exclusively
for bug fixes. This is not a bug fix; this is an addition of newly
defined functionality, which according to semantic versioning, cannot
be done in a patch release and requires an increment of the minor
version number. So there is another argument in favor of waiting until
5.4 or 6.0 here.

[1] http://semver.org/
[2] Yes, I know Lua doesn't fully comply with semantic versioning, but
typically it has done so at least with regard to the patch version,
which is the point of contention here.
