Ensure that a domonic object evaluates to True
((it exists as opposed to the variable being None)

E.g.

   def maybe_get_element():
     if some_condition:
        return Document()
     return None

   x = maybe_get_element()
   if x:
      do_something_with(x)

…to the variable being None)

E.g.

   def maybe_get_element():
     if some_condition:
        return Document()
     return None

   x = maybe_get_element()
   if x:
      do_something_with(x)

Design Decision

The __bool__ method always returns True regardless of the object's state. Consider if empty DOM objects should evaluate to False for consistency with Python conventions where empty containers are falsy.

def __bool__(self):
    # was previously falling back to __len__
    return True

Clarify boolean evaluation logic

Consider whether all DOM objects should always evaluate to True regardless of
their state. Some DOM objects might logically be considered "empty" or "false"
in certain contexts, such as when they have no children or content.

domonic/dom.py [755-757]

 def __bool__(self):
-    # was previously falling back to __len__
+    # DOM objects are considered truthy if they exist as valid nodes
+    # Override __len__ fallback behavior for consistent truthiness
     return True

__

Why: The suggestion raises a valid design consideration about the truthiness of DOM objects. While the PR's change is intentional, the improved comment in the suggestion better documents the rationale behind this choice, which enhances code clarity for future maintenance. The functional code remains unchanged.
