Thanks for the report, this has been fixed in the next version, which will be released soon.

Great, thank you!

@LebJe you may also want to update the embedded toml++; it's at v3.3.0 now and the last few releases have fixed a number of fun surprises I've discovered since the version currently used by this lib.

@SamuelSwartzberg 0.2.0 is released!

Nice, thanks again! :)
