Hi,

Grafoscopio brings inspiration from IPython/Jupyter[1][2], Leo and, of course, Pharo/Smalltalk (among others). Recently Edward Ream, the main force behind Leo, asked my about the internals of Pharo and I would like to give him a better answer that the one I gave[4] with pointers to detailed literature.

So, any details on the following question will be appreciated.

Cheers,

Offray

I'm beginning to wonder what the difference is between the Pharo way and

How does Pharo handle changes in object format or methods? How does Pharo recover from crashes due to changed method signatures, invalid calls, etc?

Edward
