StackOverflowError may happen while parsing multiline array with different types

[BOOMeranGG]

The parser seems to die (StackOverflowError) with the below. The funny thing is that with a trailing comma after the inner array it doesn't error unlike my currently opened issue. I can open another issue for this if that seems better fitting.

a = [
    "test",
    ["test"]
]
