Fail to load toml file with array-table

[oldkingOK]

Using latest Tomlet (5.3.0)

Code

using Tomlet;
...
var doc = new TomlParser().Parse("test.toml")

test.toml

[[a.b]]
name = "nick"
ishuman = true

[[a.b]]
name = "jack"
ishuman = false

Log

Unhandled exception. Tomlet.Exceptions.MissingIntermediateInTomlTableArraySpecException: Missing intermediate definition for a.b in table-array specification on line 1. This is undefined behavior, and I chose to define it as an error.

It works with test.toml:

[[a]]

[[a.b]]
name = "nick"
ishuman = true

[[a.b]]
name = "jack"
ishuman = false

While the TOML 1.0.0 specification allows us to ignore the parent node definition.

Coming back to this, I'm not seeing anywhere in the TOML spec that actually says this is allowed, and they show many similar cases which are not allowed, so I'm not inclined to allow this behavior. There's a certain lack of clarity here - you're defining, essentially, an array b of name, ishuman on a table a, but you don't define a anywhere earlier, so it's ambiguous.
