## Intro
Niva is a simple language that takes a lot of inspiration from Smalltalk.
But leaning towards the functional side.
Everything is still an object, but instead of classes, interfaces, and abstract classes, we have tagged unions,
which is the only way to achieve polymorphism.
Niva is a simple language that takes a lot of inspiration from Smalltalk.
But leaning towards the functional side and static typed.
Everything is still an object, but instead of classes, interfaces, inheritance, and abstract classes,
we have tagged unions, which is the only way to achieve polymorphism.
So basically niva is types, unions, and methods for them. There are no functions.
On an imaginary graph of complexity, I would put it here:
Go < Niva < Java < Kotlin < Scala
For example, everything except the declaration is sending messages to objects.
`1 + 2` is not a + operator, but a `... + Int` message for `Int` object.
(ofc there are no extra costs for that)
C-like: `1.inc()`
Niva: `1 inc`
So basically niva is types, unions, and methods for them.
There are no functions.

#### Variable
Variables are immutable by default.
There is no keyword for declaring a variable.
There is no special keyword for declaring a variable.
