RBMessageNode has #isInlined that returns true� not all cases where the selector is send it is optimised, so a list would be one of �possiblyoptimized� selectors�
maybe #isInlined could check first against that list to quickly return false for all the other selectors.

oh, yes, that is a problem. We started for ifTrue: to do an on-the-fly re-compiling and executing the ifTrue:, but it�s a bit of work to get it right for all cases� so we did not finish
that. But it would be possible...

Yes, you can do it per class-hierarchy� you can implement on the class side a method to parametrize the compiler:

compiler
� � � � ^super compiler options: #(- optionInlineTimesRepeat)

.. and i feel really glad that Marcus armed my idea of option specification e.g.

#(+ optionToEnable1� - optionToDisable anotherOptionToDisable + optionToEnable2 )
