[Pharo-project] I will publish SimpleMorphic in PharoTaskForces

by StÃ©phane Ducasse

Hi guys I will publish SimpleMorphic in PharoTaskForces and I suggest that we include it in the core so that it does not rot. Then I will check if I find some times to clean the first items like FillinTheBlank and friends. Stef

Some proposed to used pragmas like in settings since they work well for setting and we can also browse help with implementors.

Hi, first try Inspect on the control click menu, pick the morph and an inspector should show up. On the right side of the inspector write "self delete" and execute it.
