Is there a way to get the source key representation?

[ip1981]

Let's have a TOML file

[foo]
"x\ny" = 42
'*' = 33
"?" = 121

What I want is that, after the file is parsed, I can get the table's keys in the original form as they are written in the file: "x\ny", '*', "?". I mean literally "x\ny" , with backslash+n. Quotes maybe omitted, but I want to know what they were: single, double, none, etc.

P. S. Including in table headers:

[foo."*".bar]

[foo.'*'.bar]

You need access to a Key, for example

• Table::key
• Table::get_key_value
• Table::get_values
