You could use my methods that never get accepted. I use them all the time!

Hi all.
' Middle-left-cell || style="width: 14em;" | Middle-center-cell || Middle-right-cell' self subStrings:'|'
' Middle-left-cell || style="width: 14em;" | Middle-center-cell || Middle-right-cell' self subStrings:'||'
inspect both, they are identical.
Is this expected behavior?
Looking at the method:
char := sourceStream next.
is the "problem" in that a match is had for the single pipe character.
Is there a better way to split that string along double pipes '||' ?
thank you in advance.
