Did you know that the following appears to be Smalltalk code? Runs fine in the current Pharo.

[:a | |b| 2] value: 3

    Yes, of course they can (even though Pharo ignores the nesting and turns them into top-level temp vars, lulz)

    akuhn, it's not that easy. to begin with, in a printit they behave differently than in a method. In a method they very much behave. In a printIt, they can sort of escape their context.
