It's one line instead of four, which means blocks are much more
convenient to use in Smalltakl.  They are also much simpler in
Smalltalk, because you don't have to put all the surrounding static type
information.

In this way, Smalltalk encourages people to play with blocks, while Java
pushes in the other direction.


Otherwise, they mostly do give you the same value, as far as I know.
