The clear experience from years in this and other Python forums is that
newcomers frequently draw from the term “variable” additional, specific,
inferences that are *false* for Python.

My position is that the responsibility for avoiding terms that are
likely to encourage newcomers to draw false inferences falls to us, as
existing knowledgeable community members teaching newcomers.

To the extent that the term encourages or enables a mental model that is
significantly likely to lead to false inferences, the term is harmful
for a newcomer's learning.

That extent varies with each newcomer, of course; I'm pointing out that
the proportion of newcomers arriving here with a mental model of
“variable” which will produce false inferences is high enough that the
term is best replaced by terms that imply more-accurate mental models.
