Comment (by felix):

 As beeing discussed on IRC there is also a problem with `record-
 variants`/`coops`: here structure tags are taken literally instead of the
 variable holding the module-decorated tag name.

 Attached is a patch that modifies `record-variants` to use the tag
 variable implicitly created for a record instead of treating the record
 name directly as the tag (which will fail with modules). This patch also
 fixes some minor problems. I post this here since a few issues may be
 worth noting:

 * Jim should check whether my modifications of `record-variants` makes
 * `define-record-variant` will not work for a nonexistent record

 The latter case appears in `coops`: here we use a record-variant direclty,
 instead of shadowing an existing record definition, this is, strictly
 speaking, a hack. Now, `define-record-variant` access the record-tag
 variable, which will of course no exist, so I've added a dummy record
 definition for `coops-instance`. The other `coops` fixes should
