Hi Marcel!
Think of simulating "7/0".
I don't understand what you mean. :-) [7 / 0] ifError: [#error] returns #error. [[7 / 0] newProcess runUntil: [:c | c isDead]] ifError: [#error] does not. The only exception is signaled *in* the simulation process, it shows up a debugger, but the exception does not arrive at the simulating process.
Best, Christoph
