DreamBerd 2: Sequel to the perfect programming language

None needed, this is a drop-in replacement

Whoosh or not? It's definitely a humoristic language given some other ones:

> To avoid confusion, the delete statement only works with primitive values like numbers, strings, and booleans. > delete 3! > print(2 + 1)! // Error: 3 has been deleted

Although the feature about prefixing a variable with "previous" to get its previous actually sounds quite useful!

But also to answer your question, it uses a semi-colon for NOT:

> You might be wondering what DreamBerd 2 uses for the 'not' operator, which is an exclamation mark in most other languages. That's simple - the 'not' operator is a semi-colon instead.

I love this kind of project as it can make you rethink some basic things we're used to work with in other languages.
