Here's an error message I encountered while using participle to parse a value change dump (VCD) file. See: filmil/go-vcd-parser#2.

unexpected token "V" (expected <kwend>)

Now participle is of course correct. But it is not exactly helpful. It does not tell me which production was parsed when the error occurred. I have multiple productions that may end with keyword $end. And one of the issues may be that my grammar has started parsing a wrong production somehow.

Perhaps this is already supported?
