these are some quirks that don't align with the spec:

• values get prioritized over keys, so 1 = "one" doesn't get parsed even though it should (use quoted keys for now)
• signed hex/octo/binary integers get parsed (+0xABCD, -0o200) even though they shouldn't
• integers with invalid underscores get parsed (_123, 1__23, 123_) even though they shouldn't
• out of range integers don't throw an error even though they should, they just wrap around
