The local block variables are not a problem in Squeak 3.0.
They are a problem in some earlier versions of Squeak.

The doBlock with the three arguments is only used to write
the tuples into the transcript and it is not even needed to do
that. Replace the call of the doBlock with:

  Transcript show: args printString; cr.

and you can remove that block.

The proposal of Chris is, in my opinion, a general solution.

Cheers,
