Maybe this is the crucial point: The existing comments in `tree.def'
describe what the backend does with PLACEHOLDER_EXPRs, but they do not
tell the whole story about how a frontend is intended to use them.
I had trouble doing that in a language-independent way since we can't
assume that a reader of that file will know either Pascal or Ada. Perhaps
you might want to try a first cut at the additional documentation needed?
I may be a bit too "close to it" to be able to see what's missing.
But if you weren't able to figure this out from the documentation that's
there you are quite correct it needs to be expanded.
