Fair point, i assumed using iceberg was his idea, my apologies if it wasn't. Can't comment on the stability of bloc, other team-members did that part of the project.

OTOH, please note that iceberg was only the tip of the iceberg (i am a huge fan of the name), the IDE itself did crash many times and corrupted my image once. The formatter moved comments into other blocks which changed their meaning and combined with CTRL+Z it deleted code after cursor in some cases reproducibly.

One extra funny though harmless bug was that shift+click didn't select a range of items items in some listboxes. It selected just the new one but left the old one highlighted. I clicked a few items and sometimes it selected the whole range. When I released shift and clicked more items, it played back the clicks i made earlier and selected those items instead. We joked that smalltalk did not only invent OOP but also command queuing in strategy games. Yeah, it was mean but we couldn't imagine what code had to be behind the listboxes to cause this behavior.

So yeah, maybe someone else thought OOP students would make a good typechecker for iceberg and designed the class accordingly but what i think and say about pharo still stands.
