Description

The following is valid however tomlkit isn't able to properly handle the dual scopes:

a.b.c = 12

[a.b]
d = 34
import tomlkit

doc = tomlkit.parse("""\
a.b.c = 12

[a.b]
d = 34
""")

# looking at the doc shows incomplete data
doc  # {'a': {'b': {'d': 34}}}

# retrieving data works
doc['a']['b']['c']  # 12

# modifying data fails
doc['a']['b']['c']  = 45
doc['a']['b']['c']  # 12

doc['a']['b']['d']  = 100
doc['a']['b']['d']  # 34

Research direction

Start by reproducing the example through tomlkit.parse and compare the document view with direct retrieval and assignment for c and d. Trace the parser's handling of the dotted key and the later [a.b] table, then verify that both values appear in the document and remain independently mutable.
