graphene:with-quaternions (vars &body body)

q1 ... qn -- the newly created graphene:quaternion-t instances
body -- a body that uses the bindings q1 ... qn

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

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