[issue30637] Syntax error reported on compile(...), but not on compile(..., ast.PyCF_ONLY_AST)

[Terry J. Reedy]

Terry J. Reedy added the comment:

Python grammar is constrained to be, I believe, LL(1).  Whatever the constraint is, there are a few syntax rules that either cannot be written or would be difficult to write within the constraint.  So they are checked during compilation.  Can you suggest a couple of sentences you would have like to have seen, and where?

I might also note that not all exceptions raised by compile are literally 'SyntaxError's.
