These comments are meant to indicate which annotations each AST fragment has. However, they are rarely kept up to date and ultimately not that useful. If someone wants to know then it is easier to look at the `Annotate` module in `ghc-exactprint`where this information also exists programatically.

Hmm, the fact that this module is outside of GHC is a bit unfortunate. If I'm looking at a random GHC commit from a year ago how am I to know which annotations I can expect? I guess the testsuite?

The only reliable way is to look at `Parser.y`.
