c++ - Should main with trailing return type be avoided? -

in code example below main function written c++11 trailing return type notation:

auto main() -> int {   //...   return 0; }

question:

are there reasons main trailing return type should avoided , classical notation should preferred?

it's valid , works fine.

the issue concern is new. may confuse or surprise readers of code familiar c++98.

but works, feel free write main way if feel it.
