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.
