How did you spot those classes?

A quick investigation using ‘class-of’ and the various constructors:

scheme@(guile-user)> (class-of (make-hash-table))
$1 = #<<class> <hashtable> 9f96780>
scheme@(guile-user)> (use-modules (srfi srfi-69))
scheme@(guile-user)> (class-of (make-hash-table))
$2 = #<<class> <srfi-69:hash-table> a115000>
