Lambda Functions

Declaration

lambda<params> -> <return> (optional)
{
    ...
}

Calling

Lambdas can be called in several ways

• Assigning a lambda to a variable then calling it
• Passing it to a function

If you wish, you can specify a return type when you call it by using the arrow notation

create someFunc <- lambda<> {print_("hello!");};
someFunc();

create otherFunc <- lambda<u32 a> {
    return(a * 10);
}

print_(otherFunc() -> u32);

Captures

Lambdas capture all availible variables by reference (except this) at the location where they are written

doSomething function<fn func>
{
    func(123);
}

entry function<>
{
    create a <- 10;
    doSomething(
        lambda<u32 b>
        {
            a <- a + b;
        }
    )
    print_(a); // should be 123 + 10 = 133
}
