I'm working in latest Pharo (30577) with STON (bleeding edge) and I get MNU:SmallInteger>>isSeparator when I evaluate the code below. Is my code wrong? The idea is to make my test suite work in the memory file system.
fileSystem := FileSystem memory.
(fileSystem / 'file.txt') ensureCreateFile.
STON writer
on: (fileSystem / 'file.txt') writeStream;
nextPut: 'hi'.
STON reader
on: (fileSystem / 'file.txt') readStream;
next.
Thanks in advance.
