Would you mind saying a bit more on this?Here a simple implementation of SRFI-9, using syntax-case: [code snipped]Hi Felix,The following modification of your code works, but is generative, and so probably misses the point of what you were trying to achieve. To get nongenerativity, the underlying SRFI-9-like interface should probably be passed an extra identifier to be used as tag, instead of creating a unique tag as done below.
Thanks, this works, but (as you remark) doesn't help with the generative/ non-generative issue. Well, I'll ponder over this a little more... cheers, felix
