Returns a parser that applies function `f` (optionally taking extra input `x`) to the result of parser `a`. If `f` returns non-zero, then the parser succeeds and returns the value of `a` (possibly modified by `f`). If `f` returns zero, then the parser fails with message `e`.
Returns a parser that applies function `f` (optionally taking extra input `x`) to the result of parser `a`. If `f` returns non-zero, then the parser succeeds and returns the value of `a` (possibly modified by `f`). If `f` returns zero, then the parser fails with message `e`, and the result of `a` is destroyed with the destructor `da`.
