Re: Chaining versus cascading

Hi,

I have a question about the difference between chaining and cascading. What
would happen if you wrote this:

Html table id: 'label' with: [foo foo foo]

You see, I've left out the semicolon that the sushi store demo puts between
'label' and with. It usually looks like this:

Html table id: 'label'; with: [foo foo foo]

 

Well, the first example is sending the method #id:with: to Html table.  The second example is the equavalent of:

Html table id: 'label'.

Html table with: [foo foo foo].

 

The cascading operator (the semicolon ;) causes the next message (#with:) to be sent to the previous messages (#id:) receiver (in this case, Html table).
