[Cuis-dev] I think i found a bug in the debugger

[Hernan Wilkinson]

Hi Nicola,
 I'm sorry! I misunderstood your email! I read the subject with the word
"bug" and then went directly to the image you pasted and I thought "it is
not a bug, it is how it is intended to work" :-)
 I agree that on this example, it would be better to see 'nil' than just
nil because it is confusing but for sure there is a reason not to do it
that way... I mean, Smalltalk is a mature system and for sure there is a
reason for showing strings that way, sadly I do not know/recall that reason.
 Anyway, it is not a bug. It would be interesting to see the behavior of
the change Gerald suggested... maybe the reason for that "if" was only
"performance" (why create a new string if we already have one) and if so,
changing that behaviour would be an improvement from the UI point of view
as you suggested.

 Cheers!
 Hernan
