It'd be really cool if we could grab the name out of a JSON object like what's returned from the "Nearest Entity" Trick pair. I wouldn't necessarily mind if it required some horrific memory shenanigans to do an ASCII search, and obviously it'd be incompatible with any plans to include "Nearby Blocks" or something because lol, but there are some reasonable things you might do with a Trick like that - "find the nearest Ghast", for example, or "pick out the ores entities from a giant mass of cobble from a broken chest, and Exodus them to me."
