Wow, I must be missing a whole lot of context in that discussion...�� (instant reaction as well, lol)

- a product (CD, book, etc.) does not 'buy' - it can be bought, sure, but it has no buying��action.�� Even in another context a CD does not 'play'... aMusicPlayer.play(aCD).

- However, a��customer can 'buy' a product...��

customer.buy(aCD) -or-
customer.addToCart(aCD)
customer.checkOut(aCart)
Invoice.new(aCart), etc.��

- ... but the CD doesn't DO anything.��

- I get the idea that different products might have different behaviour when they are 'bought' - but these are, in this example, fulfillment - not the 'buy' action...��

aCDstream��might be set for download
aCDphysical might be set to physically pull off a shelf and ship
aCDcare might send an email on warranty, whatever... but let's name it better than 'buy' :)

Tim, thanks for the link - I'm always trying to expand my thinking about object modeling - discovering cool ways/things others are��thinking about...�� Now I have to go dust off all my old POS (point of sale, not piece of s#&t) code and see how poorly I may have modeled those environments!!

Thanks for the morning diversion!�� Cheers.

I saw a tweet about that, and I think that the example is misleading, maybe intentionally so.

I don't think anybody would model it that way, in any case you'd have aProduct.buy() or aProduct.addToCart(aCart).��

If you think it with the typical dog.bark() it certainly makes more sense than bark(dog).

Regards!

Hi guys - someone pointed out this article from a UK colleague which seems to be causing a flurry of discussion - but I always like the insights of this group. I had an instant reaction when I read it - but curious what people here think in 2021.
