## Summary This commit adds some additional error checking to the parser such that assignments that are invalid syntax are rejected. This covers the obvious cases like `5 = 3` and some not so obvious cases like `x + y = 42`. This does add an additional recursive call to the parser for the cases handling assignments. I had initially been concerned about doing this, but `set_context` is already doing recursion during assignments, so I didn't feel as though this was changing any fundamental performance characteristics of the parser. (Also, in practice, I would expect any such recursion here to be quite shallow since the recursion is done on the target of an assignment. Such things are rarely nested much in practice.) Fixes #6895 ## Test Plan I've added unit tests covering every case that is detected as invalid on an `Expr`. |
