    a stack of tokens which indicates whether line-ends can be statement separators also used for keeping track of nesting levels. We keep track of the closing symbol of a region. This can be RPAREN if region starts with '(' RBRACKET if region starts with '[' RBRACE if region starts with '{' ARROW if region starts with 'case' STRINGLIT if region is a string interpolation expression starting with '${' (the STRINGLIT appears twice in succession on the stack iff the expression is a multiline string literal).
