typedefは文法的に非合理的なところがあるんだけど気付いてる？

typedef std::basic_string<char, std::type_traits<char>, std::allocator<char>> string;
typedef std::mersenne_twister_engine<std::uint_fast32_t, 32, 624, 397, 31, 0x9908b0df, 11, 0xffffffff, 7, 0x9d2c5680, 15, 0xefc60000, 18, 1812433253> mt19937;
↓
using string = std::basic_string<char, std::type_traits<char>, std::allocator<char>>;
using mt19937 = std::mersenne_twister_engine<std::uint_fast32_t, 32, 624, 397, 31, 0x9908b0df, 11, 0xffffffff, 7, 0x9d2c5680, 15, 0xefc60000, 18, 1812433253>;
