$ pbpaste|docker-swift-run swiftc -Ounchecked - /tmp/--90f083.o:--90f083.o:function $s4main6primes4upToSaySiGSi_tF: error: undefined reference to 'sqrt' clang-10: error: linker command failed with exit code 1 (use -v to see invocation) <unknown>:0: error: link command failed with exit code 1 (use -v to see invocation) $ pbpaste|docker-swift-run swift -Ounchecked - [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97]
