I think the methods added to StringTest should be:
(i.e. including the dot in the suffix)

Method 6.2

testSuffixFound
  self assert: 'readme.txt' suffix = '.txt'

Method 6.3

testSuffixFound
  self assert: 'readme.txt' suffix = '.txt'.
  self assert: 'read.me.txt' suffix = '.txt'

I think that it's incorrect stating that the literal 'foobar' is stored once.
Therefore "trouble at: 'foobar'" will raise an 'key not found' exception.
At least it does in my 3.9 development image.

Hm, the identity 'foobar' == 'foobar' returns true.
So I would say that the literal string is stored once. Sorry about that.
But why is "trouble at: 'foobar'" raising an "key not found" exception then?

Anyone?

Regards, Has.

I think that you will find that it depends how you compile it.  If  
you compile (i.e., "do it") the whole script at once, it will work.
However, if you compile the at: put: and the add: in separate doits,  
then they will get separate copies of the literal.

You're absolutely right. But the way it's presented in the book,
there's no dot between the "trouble at:" messages and there's "print
it" right after each one of them.
That may be a bit confusing for me and others readers.

Regards, Has.

OK, I have marked it as a to-do to fix for the next edition.  I think  
the example must be re-written to make it easier to reproduce.  It is  
a shortcoming of our approach to displaying the examples.

Note that the generated test is unambiguous, but more verbose.

test453
	| a b trouble |
	a := 'foobar'.
	b := a copy.
	trouble := IdentityDictionary new.
	trouble at: a put: 'a'; at: b put: 'b'.
	self assert: [ trouble at: a ] value printString = '''a'''.
	self assert: [ trouble at: b ] value printString = '''b'''.
	self assert: [ trouble at: 'foobar' ] value printString = '''a'''.

Thanks Has,

It looks like Andrew has already changed a lot of things in this  
chapter, but I haven't had time yet to check it.

Hi Oscar,

No problem. I'm slowly working my way through SBE. It's a lot of fun.
