Its use is to specify a non-standard subscriber.
In VW it is pretty much mandatory when using weak subscription, as VW subscribes the block.
In Pharo it's much less useful, both because the at the moment weak when:do: doesn't work, but also since Pharo subscribes the block's receiver by default, which is what you want in 95% of cases.
Still nice to have around in the edge cases one might still need it though.
