I agree that enumeration is more useful but it wouldn't be bad to have something in there to indicate the 1-index nature, such as

�� 'abcd' at: 2 will result in $b
That's all I was suggesting.

Actually, having some cheat sheet on basic enumeration wouldn't be bad as that is a real strength of Smalltalk. Mention and illustrate what do: collect: and select: do. Then mention that there are other ones like count: and sum:.

Cheers,

Jeff

I use Pharo since 1 year now and I had to use indexes only 3-4 times. I
think it is more important to say that Pharo have Collections with an
awesome API.
