`thisContext tryNamedPrimitiveIn: BalloonEngine>>#primGetFailureReason for: BalloonEngine new withArgs: #()` should answer the same as `BalloonEngine new primGetFailureReason`, but instead the meta primitive fails with error 106, which is not even documented in `Context>>#tryNamedPrimitiveIn:for:withArgs:`. The same is also true for at least `primFlushNeeded`. In consequence, one cannot debug/simulate some Balloon code at the moment ...
