Hi sven
I think that I will have to hack my own, I was just surprised that we do not
have a nice way back
from tokens back to code. (not talking about quote inside strings).
String streamContents: [ :s |
#('self' 'classVariables:' ${ #A $. #B $})
do: [ :each | s print: each ]
separatedBy: [ s space ]].
'''self'' ''classVariables:'' ${ #A $. #B $}’
