Assignment

A value can be given a name using let.

let x = 1;

In the example above, the type of x was inferred to be an integer i32, but in cases where you want to be explicit, you can specify the type.

let x: i16 = 1;

Mutability

Variables in Mew are immutable by default.
To be able to update an already assigned variable, use the mut keyword.

let mut x = 1;
x = 2; // Variable can now be updated
