// Tests a case where parsing within an incorrectly predicted paren expression
// (the "outer" assignment) would put the parser in an invalid state when
// reloading a stored prediction (the "inner" assignment) and cause a panic when
// generating the unclosed delimiter error. See the comment in the issue for
// more details.
