I think there is a lightweight alternative that isn't in the wiki and that doesn't require changing the language:

• use an OPAQUE helper function to hide unsafePerformIO
• require Typeable a: no risk of having a top-level forall a. IORef [a] and segfaults
• use HasCallStack to guarantee that each call is unique: avoid CSE of global variables

GitHub doesn't currently support updating all comments made on one account
to be made by another account. I made a lot of comments with my work
account, and people keep tagging my work account on issues, but I'd like
them to start referencing my personal account.

So for now, I'll just get every comment I made on my work account and add
a blurb to the beginning about using my personal account.

Run with:

brandonchinn178

Build with the following command:
```bash
hadrian/build -j9 --freeze1
```
Then
```
GHC=/path/to/repo/_build/stage1/bin/ghc ./run.py
```

Note: `--flavour=perf` and `--flavour=bench` weren't working for me on my M2 Mac.
