- _repr() method added. if _str method doesn' exists on an instance,
it'll try to call _repr() to make a string.
- number.isint(), number.isbyte() method added
- [], []= operator were added.
pkVar is removed and slots (like wren) are implemented for accessing or passing pocketlang values to C and vice versa. Yet all the slot related functions are callable at runtime (a fiber is associated with the VM) which needs to be refactored to allocate slots even if it's not runtime, to let users make use of the pocketlang values before or without running a function.
