-/* Notes on f-strings: f-strings are strings prefixed with f (e.g. f'') that may
-   have arbitrary expressions in {}.  The tokens in the expressions are lexed as if
-   they were outside of any string.  Expressions may contain { and } characters as
-   long as there is a closing } for every {, may be 2+ lines in a triple quoted
-   string, and may have a formatting specifier following a ! or :, but both !
-   and : are valid inside of a bracketed expression and != is a valid
-   expression token even outside of a bracketed expression.
-
-   When in an f-string expression, the lexer keeps track of the state value of
-   the f-string and the nesting count for the expression (# of [, (, { seen - # of
-   }, ), ] seen).  f-strings may be nested (e.g. f'{ a + f"{1+2}"') so a stack of
-   states and nesting counts is kept.  If a f-string expression continues beyond
-   the end of a line, this stack is saved in a std::map that maps a line number to
-   the stack at the end of that line.  std::vector is used for the stack.
-
-   The PEP for f-strings is at https://www.python.org/dev/peps/pep-0498/
