how do i read this regex? https://github.com/authzed/spicedb/pull/1254/files#diff-daf9cb335c0ae98207245de93841668f2a4bf8025073e2cdf0af2cdf7589a18e I tried to put it into an online regex explainer and it complained about

\\-=

as being an invalid range because "\" comes after "=" in the ascii character table.
