I was looking at this, but I feel like adding a new class might be a bit of an
overkill for this situation. Looking at the code in `lib/Transforms`, there are
70 uses of `report_fatal_error` and 17 uses of `Ctx.diagnose(...)`. The latter
seem to all be more complex diagnostics than just printing out an error
message. Do you think I should nevertheless use `Ctx.diagnose` for this message?

Done.
