Thinking about this, I don't believe allowing non-string keys here are a desirable feature.
It's tempting not to check for this in some cases where it does no harm (skipping the check shaves a few microseconds off execution time), but I think the reference manual should require strings here and we would do well to tighten the implementation. We may find though that this has accidentally become a gray area that some code has come to depend on, so we may have to deprecate it. This really depends on how much code depends on it though, there's no strict rule for such cases.
