-\section[PlainCore]{``Plain'' core syntax: the usual parameterisation}
-
-This module defines a particular parameterisation of the @CoreSyntax@
-data type. Both binders and bindees are just @Ids@. This is the
-normal thing.

-The ``Core things'' just described are parameterised with respect to
-the information kept about binding occurrences and bound occurrences
-of variables.
-
-The ``Plain Core things'' are instances of the ``Core things'' in
-which nothing but a name is kept, for both binders and variables.
