YAMA 0007 - Additional features for structs

• Author(s): Bhathiya Perera
• Status : ✅

Structures are at the moment can be created as follows

@onstack
class Banana:
    color: int
    origin: int

# Orange is a heap allocated class
class Orange:
    color: int
    origin: int

Item 1 - Allocate single object on heap ✅

a: Ptr[Banana] = make("Banana")

b: Orange = make("Orange")

Item 2 - Create structures or classes

a: Banana = Banana {color: YELLOW, origin: SRI_LANKA}

struct Banana a = (struct Banana){.color = YELLOW, .origin = SRI_LANKA};

b: Orange = Orange {color: ORANGE, origin: SOUTH_AFRICA} 

struct Orange* _temp = calloc(1, sizeof(struct Orange));
_temp->color  = ORANGE;
_temp->origin = SOUTH_AFRICA;

struct Orange* b = _temp;

Item 3 - Introduce struct keyword, desugar to @onstack class ✅

struct Banana:
    color: int
    origin: int
