Previously variadic tuples were displayed as `builtins.tuple[T]`, which is misleading. That syntax ordinarily indicates a tuple with a single element. This change adds the `...` ellipsis when formatting. The formatting of non-variadic tuples is unchanged (e.g. `Tuple[T, U, V]`).

There was a problem hiding this comment.
This can also be written as .format(t.args[0].accept(self)), but this seems prettier.
