Hello,

> I tried changing all to `#:init-value', but the result was the same.

Imo, using your definitions, guile should return 'foo, not 42.

But note that you do not define a getter in <bar>.  Still using your code the
following will work:

	(foo-a (make <foo>))
	(slot-ref (make <bar>) 'a)

Then if you define a getter..., you also get the expected result

Cheers,
David

	(foo-a (make <foo>))
	(foo-a (make <bar>))

	$2 = foo
	$3 = bar
