This doesn't seem to be supported right now?

julia> texparse(raw"\sqrt[3]{2}")
ERROR: TeXParseError: end of string reached with unfinished argument_gatherer

\sqrt[3]{2}

It is indeed not supported.

It is on my list, but since it requires the support for optional argument in commands, I will need to add some rules to the parser and it is always a bit tricky.
