then

browser transmit to: #namespaces; andShow: [ :a | a tree display: [ :model | model allNamespaces select: [ :each | each isRoot ] ]; children: [ :namespace | namespace childScopes ]; format: [ :namespace | namespace stubFormattedName ] ].

why format: is not named formatItem: if this is what is does? How as a reader should I know that format is sent to an item?
