Hi this warning is just that printOn: is working on a stream and when we do printOn: aStream aStream nextPutAll: x printString printString creates yeat another stream then ask the contents and passes it to the first one printOn: aStream x printOn: aStream is faster and cleaner in that case.

I started working through PBE8, and in section 3.13 there is a method:
Counter >> printOn: aStream
super printOn: aStream.
aStream nextPutAll: ' with value: ', count printString.
But it returns two warnings:
[printString] No printString inside printOn
Use cascaded nextPutAll:âs instead of #, in #nextPutAll:
It has the option to automatically resolve the cascaded nextPutAll: which results in:
printOn: aStream
super printOn: aStream.
aStream
nextPutAll: ' with value: ';
nextPutAll: count printString
But it still has the warning about printString.
