=============== Diff against Files-bf.1 ===============

Item was added:
+ ----- Method: FileStream class>>fileNamed:do: (in category 'instance creation') -----
+ fileNamed: fileName do: aBlock
+ "Avi Bryant says, ''This idiom is quite common in other languages that make heavy use of closures (i.e. Lisp (with-file 'foo' (f) ...) and Ruby (File.open('foo'){|f|...})).  It's time Squeak had it, too.''
+
+ Returns the result of aBlock."
