Playing with new C++ features to see if I can write a tokenizer / parser without boost.

tokenize.cc

#include <iostream>
#include <string>
#include <vector>

auto member_of(const std::vector<char> &cs) {
  return [=](const char c) -> bool {
    for (const char &x : cs) if (c == x) return true;
    return false;
  };
};

auto main(int argc, char **argv) -> int {
  if (argc == 1) {
    return -1;
  }
  auto s = std::string { argv[1] };
  return 0;
}
