How to get symbol name from a `SymbolResult`

I may be overlooking something obvious, or just have spaced on this...

I want to transform the `ParseResult` for combining with additional failures that will be grouped by symbol name.

I can get the `SymbolResult` from `ParseResult.Errors.First().SymbolResult`

However, I do not see how to get the `Symbol` from the `SymbolResult` (which seems odd enough I am pretty sure I have overlooked something).
