This doesn’t list which tags cause special compiler behavior, only which<br>
ones are used by GHC in general.<br>
<br>
Also, it is by no means clear that this list is comprehensive. It seems<br>
that its authors were partly even unsure about tag meaning: the entry<br>
for tag `a` has a question mark.<br>
<br>
Finally, this list leaves questions open. It sometimes only mentions<br>
compiler components to which certain tags are related but not for what<br>
kinds of uniques they are actually used (and not even whether said<br>
uniques are introduced or used by the mentioned compiler components).<br>
<br>
All the best,<br>
Wolfgang<br>
