‘type’: A module system type representing the module set as a submodule,
to be extended by configuration from the containing module set.
This is also available as the module argument ‘moduleType’.
‘extendModules’: A function similar to ‘evalModules’ but building on top
of the module set. Its arguments, ‘modules’ and ‘specialArgs’ are
added to the existing values.
