gio:with-resource ((resource path) &body body)

resource -- a g:resource instance to create and register
path -- a pathname or namestring with the path of a file to load
body -- a body that uses the binding resource

The g:with-resource macro allocates a new g:resource instance, loads the resource from a file, register the resource with the process-global set of resources and executes the body that uses the resources. After execution of the body the resource is unregistered from the process-global set of resources.
