Trying to index an array type with .get(...path)
const schema = type('string[]');
console.log(schema.get(0).expression);
const schema = type('string[]');
console.log(schema.get(0).expression);
The code below prints "string | undefined" which at first kind of makes sense but after thinking about it, I feel like it should just be "string". While regular array indexes can return undefined, types are never actually turned into real values so an index can never actually fail. It also doesn't match TypeScript types where indexing an array type like string[][0] equals string. My use case is that I'm building an automatic form generator where I am using .get(...path) to get a specific part of the schema in a deeply nested object schema. I want to be able to effectively get the array's type but to my knowledge it's impossible to do so because any array index always adds | undefined so I cannot differentiate between string[] and (string | undefined)[] for example.
