Slots only drive access to the instance variables and the association "literal" is already a message send. But I guess you wold be able to do such behavior with own Opal plugin. -- Pavel 2017-03-01 15:56 GMT+01:00 Ben Coman <btc@openinworld.com>:
I'm not sure I'm thinking straight, but I wonder... Can you put Slots inside an Association?
For example, could have two slots x and y, and then be able to do the following...
(x -> y) substitute: (1 -> 2). self assert: x equals: 1. self assert: y equals: 2.
So the association method #substitute: assigns into the relevant variables.
And even better if you could do... (x -> y) := (1 -> 2). and... { x. y ) := #(1 2).
For example, when you're hacking fast and want to return two values from a method without mucking around with creating an object for this, it might look like... myCalc ^#(1 2)
but instead of... result := inst myCalc. x := result at: 1. y := result at: 2.
you could do... { x . y } := inst myCalc.
