Item was changed:
  ----- Method: UUID class>>fromString36: (in category '*smbase-macsafe') -----
  fromString36: aString
  	"Decode the UUID from a base 36 string using 0-9 and lowercase a-z.
  	This is the shortest representation still being able to work as
  	filenames etc since it does not depend on case nor characters
  	that might cause problems."
