graphene:with-boxes (vars &body body)

box1 ... boxn -- newly created graphene:box-t instances
body -- a body that uses the bindings box1 ... boxn

The graphene:with-boxes macro creates new variable bindings and executes the body that use these bindings. The macro performs the bindings sequentially, like the let* macro.

Each box can be initialized with values using the syntax for the graphene:with-box macro. See also the graphene:with-box documentation.
