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 ;)
