Guile 1.6, goops incompatible with ice-9 syncase

Guile 1.6, goops incompatible with ice-9 syncase

[Daschbach, John L]

It appears that the ice-9 syncase module breaks goops.  The following is an
example
The Options: line and the "not keyword" are display statements I put in the
goops.scm
file to try and debug the problem. 

The slib (require 'macro) package does not generate the error, and so I have
switched to
using it rather than the ice-9 syncase module.

It is possible I am doing something wrong.

The reason is that hitherto standard Guile macros has not played well
together with syntax-case macros.

Guile-1.7 now includes a change which make them play better together.
In particular, goops should work OK now.

Best regards,
