Well that's a different thing! It gives same error for me too.

So as

 =C2=A0 $ echo -e '123' | lua
 =C2=A0 lua: stdin:1: unexpected symbol near '123'

What result you expect?

"lua" program in interactive mode silently places expressions
inside "print()". That's neat feature to use it as calculator.

But neither "[[\ntest\n]]" nor "123" is valid Lua code:
they are expressions, not statements.
