Now we shouldn't dig into having a system running without condition and loops inlined by the compiler, because this is too much work (for example as Marcus said loops on all objects should not create an object (even a context) ...). If we really want that we will invest time. But right now it is not a priority.

You need to see that the system *never* ran without optimising ifTrue: &co, so getting that to work is a real project in itself… and it will be *extremely* slow, of course.

And it does not even help for the problem, because Fuel ran fine in the past. They two things are just not related at all.
