It makes sense since source code for us is of course not just a string, but it's surprising nonetheless. /back to lurking - Bert -

Guys, is this a fool's day hoax? ;) I think we shouldn't get agitated because of stuff like this. It doesn't matter what origin the code has. We fix it and then its done. That's how we make progress. And it's supposed to be fun too!

I think this was all fixed already in 1.1... (Object>>#halt) asString class --> ByteString. There is no asText. but #getSource return a Text (for formatted methods, of course) (Object>>#halt) getSource class So not too bad.

More seriously it would be nice to have a solution. After may be string and text can share a common interface and the current situation is kind of ok. Does anybody have a larger view on the problem and possible solution? Stef
