# New feature (Jan 2022)

## Relaxed words in alt/loop conditions

Before this new version, when you need to put more word in the between the parentheses, you have to use a "string", such as `for("record in records")`.

Since this version, you can use something like this `for(record in records)`. There is no check in the words as long as they are valid `atom`s.

The same thing applies to `if`

such as `if(instanceOf x == XClass)`

The following can be an `atom`:

1. Number (1, 1.0);
2. Boolean (true, false);
3. ID, anything that can be a variable name in Java, such as a1, xyz;
4. STRING ("hello world")
5. NIL (null)
6. Operators (+, -, \*, /, ==, &&, ||, `new`, >, >=, <, <=)
