I don't really agree with that, trying to use an undeclared
object/variable/whatever :
Python 3.7.7 (default, Aug 22 2020, 17:07:43)
[GCC 7.4.0] on netbsd9
Type "help", "copyright", "credits" or "license" for more information.
>>> print(name)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'name' is not defined

You can say it's not the "declaration" the issue, it's the "definition",
that's just a matter of vocabulary and it does not answer the question.
In many non declarative language, if I do print($var), it just prints
and undefined value with returning an error.
