Comment(by igloo):
Annotations are pragmas, which we haven't historically had extensions for.
Some options:
* Do nothing.
* Ignore (but warn about) `ANN` pragmas if `TemplateHaskell` is off (I
infer from the docs that they rely on TH). If they are a well-behaved
pragma then ignoring them won't affect the correctness of the code.
* Add an extension for annotations.
* Add an extension for each pragma GHC knows about.
