[self-interest] documentation!

[David Ungar]

Great examples. But you omitted the source code.

Here are some:

in traits collection:
	addAll: c = ( c do: [ |:v. :k| add: v WithKey: k ]. self)

c is anything that responds to ‘do:', and the collection gets each element of c added to it. That’s what I would expect one could get from reading this code.

What responds to ‘do:’? Use implementors. You get lots of implementors, telling you that many things are possible for c, including:
sets, dictionaries, collections, lists, etc.

What does ‘do:’ do? That’s where a knowledge of Smalltalk would be helpful.
But you could run this:

'abc' do: [|:x| x printLine] and see what happens.

Perfect? Far from it. But there are techniques and ways of thinking that are different from what most people are used to.

3 do: [|:x| x printLine] 

will work. More things tend to work with more things than in most other systems.
