[Bug] Syntax error with custom types in has declaration

[musab-mah-7]

Describe the bug

The declaration has some: priv T; results in a syntax error when T is a custom type. However, this syntax works without issues for primitive types like int or str. This inconsistency needs to be addressed.

To Reproduce

1. Create an object with a custom type using the has declaration.
2. Attempt to compile or run the code.

Expected Outcome:

The syntax should be consistent, allowing custom types in the has declaration without errors.

Correct Syntax Example:

obj Shape {
has :priv shape_type: ShapeType;

has :protect radius: float,
    area: float;

has name: str;

}
