22: Lambdas

Lambdas are syntactic sugar for in-place delegates.

|PARAMETERS| {
    DELEGATE_FUNCTION_SCOPE
}

Example:

var items = [1,2,3,4,5,2,3,4,5,3,4,5,4,5,5];

var only5s = items.filter(|item| { return item == 5; }).array;

Same as:

var items = [1,2,3,4,5,2,3,4,5,3,4,5,4,5,5];

fn bool filterFn(int item)
{
    return item == 5;
}

var only5s = items.filter(filterFn).array;
