Exception when run the same sub-parser in different places.

[3da]

What's the reason of this line?
throw new ParseException(i.Memos[p].ToString());

It broke my parser. When I changed it to
return (IResult<T>)i.Memos[p];
everything started work as expected.

Hi! We might need some more context - where's that line, and what is your parser doing? What's the exception look like? Cheers!

Hello.
This line is here:

Sprache/src/Sprache/Parse.cs

Line 391 in a286cb3

throw new ParseException(i.Memos[p].ToString());

I experienced the same error. My case was using Ref inside an Or like .Or(Parser.Ref(() => ...
This threw an exception along the lines of "Successful parsing of ".

Modifying the above line fixes the error (i.e. no longer throws exceptions on successful parsing).

Why was this closed? The above error has not been fixed?

This is what I had to do to allow all tests to pass (at the position @3da provided):

if (i.Memos.ContainsKey(p))
{
    var pResult = i.Memos[p] as IResult<T>;
    if (pResult.WasSuccessful)
        return pResult;
    throw new ParseException(pResult.ToString());
}

Great, thanks @r1sc - think I misread your reply above, when I closed this 👍
