The announcement of 4.0 sais that they work, and we have been using them for some time in the implementation of Live Robot Programming without issues. Sorry, I don’t remember where the examples are, Marcus made me one when I asked about them ;-) Have a look at the LiteralVariable class, I think that is a good way to start.

Hi,

what is the current state of slots? I found a message by Marcus that it's not ready but that was December; has anything changed? Is there some tutorial/examples? Are there known problems?

Thanks, Peter

Yes, I fixed a lot of bugs and implemented many things… the status is that everything works but the more complex example of virtual slots that map to a hidden base slot. (even that works, what does not work is when removing/adding slots after there are already some). The trello show what needs to be done: https://trello.com/b/d59lgZFB/slots I will work on this now step by step in Pharo5

Is there some tutorial/examples? Are there known problems?

Tutorials: Not yet, but it is in a state that I can start to write them. Examples: yes. see Slot-Examples Slot-Examples-Associations and the related tests. Known problems: the one mentions above: property and boolean slot examples are not yet finished / need some more base level support. Marcus
