A non-standard extension is provided to supply a default global environment if the `environment` argument is not specified.
#create-environment
(create-environment vars values)
A non-standard function to create a new environment on top of the default one.
`vars` is a list of identifiers in the new environment, and `values` is a list of each value assigned to each identifier.
#setup-environment
(setup-environment)
A non-standard function to initialize a new global environment.
