did you know there's no limit to how many if let statements you can have in #rust? you can just keep adding more. nobody can stop you
an if statement with nine let statements. it reads: if tile_entity.get("id").is_some_and(|id| id == "minecraft:sign") && let Some(fastnbt::Value::Compound(front_text)) = tile_entity.get("front_text") && let Some(fastnbt::Value::List(messages)) = front_text.get("messages") && let Some(fastnbt::Value::Int(x)) = tile_entity.get("x").cloned() && let Some(fastnbt::Value::Int(y)) = tile_entity.get("y").cloned() && let Some(fastnbt::Value::Int(z)) = tile_entity.get("z").cloned() && let Some(sign) = self.blocks.iter().find(|block| block.position == Xyz { x, y, z }) && let Some(sign) = new_blocks.get(sign.id) && let Some(properties) = sign.properties && let Some(properties) = new_properties.get_mut(properties)

is there actually no limit or is it stupidly high, like java and its limit of 255 parameters to a function call?

it just works ... prints out the loop_count of optional values.

Used random number generation to make sure the compiler wasn't making it vanish in a puff of logic

A screen shot of a terminal showing a run of the program linked in the gist above with the loop_count set to 10. It prints out ten lines with a line number and a random number in a Some

so it does crash rustc with a stack overflow if you set it to 65536 loops but that doesn't seem entirely unreasonable honestly.
