go version

What happened?

I got an error.

What should have happened instead?

The error I received should tell me where in the very large bytestream it was parsing,
it encountered a parsing error.

Please provide any additional information below.

I checked the source tree on and this still seemed unimplemented.

func (e *SyntaxError) Error() string { return e.msg }
Should be something like:
func (e *SyntaxError) Error() string { return fmt.Sprintf("%s at offset: %s", e.msg,
or similar.
