In general, I’m setting something to null when I want to avoid an “Undefined symbol” notice, I am sure it is not a bug, and I don’t want to scatter my code with isset() or ?? checks. * In any case, the removing of the autovivification behaviour MUST be preceded by a period of deprecation notices. —Claude
