So, pretty much whether everything is being applied right to left vs being applied left to right? Personally I like chaining because, since I read going right

  I wasn't clear, but I meant that mostly as a comment to: > This is always what I thought OOP should be, but could never put my finger on. I'm not sure what Simula did, but at least in Smalltalk this is how OOP have worked :-) > So, pretty much whether everything is being applied right to left vs being applied left to right? I'm not sure that's the best takeaway; consider: $ gst GNU Smalltalk ready st> 2 * 3; * 3; * 3 6 st> 2 * 3 * 3 * 3 54 Now, if the object on the far left was some kind of accumulator/container, the effect of sending something like three "add the number 3" would be similar to chaining. But even if you mulitply the number 2 by 3, three separate time, 2 * 3 still equals 6. In fact, in order to get chaining with keyword messages, you apparently need to define it, or especially adapt eg: containers to return ^self. But as should be obvious, I'm not very familiar with Smalltalk. Some more on the subject: http://blog.3plus4.org/2007/08/30/message-chains/ http://blog.3plus4.org/2007/08/30/message-chains/
