Correct. This is what the documentation says it should do.
| After reading a line, Lua first try to interpret the line as an expression.
| If it succeeds, it prints its value. Otherwise, it interprets the line as
| a statement. If you write an incomplete statement, the interpreter

Because '=' is replace by 'return'.
