Test on toml-v0.4.0 example

## Inline Table

# Inline tables provide a more compact syntax for expressing tables. They are
# especially useful for grouped data that can otherwise quickly become verbose.
# Inline tables are enclosed in curly braces `{` and `}`. No newlines are
# allowed between the curly braces unless they are valid within a value.

[table.inline]

name = { first = "Tom", last = "Preston-Werner" }
point = { x = 1, y = 2 }

My tests has the above inline block, it fails by using tomland-1.1.0.0

uncaught exception: IOException of type UserError
user error (ParseException "61:8:\n   |\n61 | name = { first = \"Tom\", last = \"Preston-Werner\" }\n   |        ^\n\"name\" :| [] is not a child key of \"table\" :| [\"inline\"]\n")

@leptonyu Thanks for reporting the issue! That was unexpected 😕 We will improve our test-suite and fix the bug. Could you also provide the link to your tests, so we can test before releasing a new version to Hackage?

@leptonyu Nice to have an example! I've changed the title of this issue to implement more robust testing.

Sorry about that. For this specific issue, adding a try at the right place fixes it. I'll do a PR, I should also probably add all official examples and make sure they are fine.

I have one uncertainty about this situation though. Should

[table.inline]
name = { first = "Tom", last = "Preston-Werner" }
point = { x = 1, y = 2 }

be interpreted as one table table.inline containing two sub tables name and point, or should it be considered as three separate tables on the same level? The official documentation says:

name = { first = "Tom", last = "Preston-Werner" }
point = { x = 1, y = 2 }
animal = { type.name = "pug" }

The inline tables above are identical to the following standard table definitions:

[name]
first = "Tom"
last = "Preston-Werner"

[point]
x = 1
y = 2

[animal]
type.name = "pug"

Following this definition, the table should be three different tables right? That's what my parser does (and will do correctly as soon as I fix the current issue).

I think this is correct but I never found a satisfying explicit answer or counter-example. What do you think?

[leptonyu]

Reviewing the following issue, I think you are right. The motivation of inline tables is not to supporting sub tables, but to simplify tables.

Thanks for looking into it!

@leptonyu This was fixed by @jiegillet. I've uploaded tomland-1.1.0.1 to Hackage:
