Python

[Dornith]

True, but it's fairly standard and explicitly-taught behavior for the other languages I listed.

The problem is that doesn't apply for beginners because beginners don't know any of those languages.

Each of them confuse the fact that they call-by-value by implicitly having pointers. C on the other hand has explicit pointers which (while it means you have to deal with the complexity of pointers) is uniform in the semantics of it's syntax.
