Realized that if i want to use malloc and free i either have to make some sort of interface that lets you use a custom allocator and deallocator or just use them by default. Maybe later it would be cool to change it to that but for now is out of the scope of my project. # Tipos: # feat, fix, refactor, docs, style, test, chore
