     This release fixes a bug in the parser where code of the form `#a in #b in c` caused a crash. This code now causes a syntax error instead. Private identifiers are allowed when followed by `in`, but only if the operator precedence level is such that the `in` operator is allowed. The parser was missing the operator precedence check.
