Comment:

 Fortunately this one was an easy fix. I noticed that generated names (e.g.
 beginning with `$tc` or `$tr`) were turning up in the autocomplete after
 defining datatypes interactively, so I fixed that too. It's a tiny patch,
 so maybe worth backporting to 8.0.1? But the bug is fairly obscure, so not
 a disaster if that's too much trouble.


 > Even if you enable `OverloadedLabels`, the `#labels` don't show up in
 the auto completion.

 I've not changed this; I think it's the correct behaviour. A `#label` is
 not an identifier, it's a separate syntactic form, and there's no obvious
 basis for auto-completing it.
