Good point.

Please take a moment to:
1. go to Ulysses
2. follow the account creation link
3. create an account on fogbugz
4. log in
5. create an issue report with:
�� a. the vm version
�� b. the image version
�� c. your platform
�� d. your social security number
�� e. mother's maiden name
�� f. name of first pet
�� g. and, a reproducible way to cause the error
6. (optional, but preferable) followed up by a slice with tests
�� a. re-log-in to fogbugz
�� b. go back to the issue page because the fogbugz login page probably
didn't redirect you to the issue
�� c. add whoever is assigned as another person to notify because they will
paradoxically not be included by default
7. (if 6) add class comments to classes that you didn't modify - and
possibly have never heard of - to make the monkey happy
8. Weigh in on whether Pharo is or is not "Smalltalk" AND/OR whether a
tomato is a fruit or a vegetable
9. Cross fingers and wait (but not as long as in Squeak)
10. Try to remember what you were doing before you fell down the rabbit hole
11. Check email for VPRI's final STEPS report while waiting

IN CASE OF EMERGENCY: insert beer between or during any other step OR
remember that we (meaning the Smalltalk, Smalltalk-inspired,
Smalltalk-channelled, Smalltalk-related, and/or Dynabook-related identified
persons and possibly spouses and probably children under 17.5) still have it
far better than the rest of the programming world

;-P (hopefully obviously)

Oh, but wait, I opened some bug reports once upon a time...

I just rediscovered http://bugs.squeak.org/view.php?id=5707 which links to http://bugs.squeak.org/view.php?id=7194

Not my fault if a forked happened ;)

To continue around this very same example, every one knows that this should fail:
������ 'hello' copyReplaceFrom: 3/2 to: 5/2 with: 'world'.
Indeed, only integers should be used as indices!

It should fail equally whether the argument is wide or not as you can see:
������ 'hello' copyReplaceFrom: 3/2 to: 5/2 with: 'world' asWideString.

Well yes, maybe non integer indices could be used, but Character>>negative is not understood

It should fail equally whether the receiver is wide or not as you can see:
������ 'hello' asWideString copyReplaceFrom: 3/2 to: 5/2 with: 'world' asWideString.

A good lesson: tricky hacks like this always come with a price:
������ index isNumber
������ ���� ��ifTrue: [^self at: index asInteger]
������ ���� ��ifFalse: [self errorNonIntegerIndex]

The sooner failure, the better failure ;)
