There are better ways of a tolerant comparison. We already have https://github.com/prometheus/prometheus/blob/main/promql/test.go#L637 in the Prometheus code base. Perhaps that's easy enough to just copy over here.

Or depend on https://github.com/beorn7/floats :o)

Thanks, @samjewell. As you might have guessed from our personal communication, this touches two areas I have been thinking a bit about in the past, but never refined my thoughts...

In the stated example, this was for performance reasons, but not because of a proven performance gain, rather to prevent every reader to think about it again ("Is this optimized...

As discussed elsewhere, while "timezone" in the context of the TZ database indeed refers to a location (e.g. "Australia/Sydney"), the general understanding of "timezone" is more ambiguous. In many other...

I think it should be possible to create a silence for an empty label, which is equivalent to an non-existing label, or in other words, it gives you a straightforward...
