Hi Bernhard,<br>
<br>
The original implementation of Text from Smalltalk-80 uses RunArray
only. RunArray is a space optimization, as usually the same text
attributes are used by many consecutive characters. But it is
expensive in time, and I found it to slow down significantly the
styling of long Smalltalk methods. Hence, #optimizedForMutationSpeed
and RunNotArray.<br>
<br>
Any code using Text should work the same using any of them (except
for the speed / space tradeoff).<br>
<br>
What problem are you seeing with RunNotArray? How can I reproduce
it?<br>
<br>
Thanks,<br>
