Toy programming language

Simple dynamically typed language.

In this small language all functions are first class objects. Structure and function declarations are missing, that's why one must use this way:

x = <function or structure object definition>

There are four types:

Int, Double, String and Boolean.

Also we have special value: Undefined.

Syntax overview

Variable declaration:

x = 10;

Struct definition:

x = [
    y = 1;
    z = 2;
];

Function definition:

f = (y = 1) => {
    y + 1;
};

For generator:

for (i <- 1 to 10) {
    println(i);
}

While cycle:

while (true) {
    println(1);
}

If expression:

x = if (1 < 2) {
    10;
} else {
    12;
};

Call expression:

f = () => {};
f();

Invoke expression:

s = [x = 1;];
println(s.x);
