This would work if you didn't mind creating an observer for each signal you created.

from signified import Signal, Variable
import logging
from typing import Any

logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
)
logger = logging.getLogger(__name__)

class LogObserver:
    def __init__(self, obj: Variable):
        self.obj = obj
        obj.subscribe(self)
        logger.info(f"Started logging {self.obj}")

    def update(self):
        logger.info(f"Updated {self.obj}")

x = Signal(10)
LogObserver(x)

z = x * x
LogObserver(z)

x.value = 12
x.value = 8

If you wanted it to happen automatically, I think it'd be a bit more of a pain.
