graphene:with-planes (vars &body body)

plane1 ... planen -- the newly created graphene:plane-t instances
body -- a body that uses the bindings plane1 ... planen

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

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