 From your question it was not clear as for what purpose you want to 
convert date to string. If you get an error, try to examine walkback and 
post it here or to squeak-dev mailing list if it is more general thing.

Feel free to ask question as why 2 plus 2 is 4. I witnessed that even 
masterful developers have hard times to answer simple questions. But in 
your case there must be something that needs to be brought to the light. 
Date is derived from Magnitude and is then sortable: "Date tomorrow > 
Date today". You can try with SortedCollection:

sc _ SortedCollection new.
sc addAll: {Date tomorrow. Date today}.
