proposed "auto" extension, to eliminate the redundancy? I'd propose something like macro functions:

And closer to Bjarne's proposed auto extension:

template <typename ParserT, typename SkipperT>
auto error_skipper_p(ParserT const& parser, SkipperT const& skipper)
    -> cpp_guard(parser)[skip_error_handler(skipper)];

Without the redundant body { ... }. The return expression says it all
in most cases.
