My reaction, without thinking much, and being fuzzy on a lot of things is that part of the point of guile is that it is Scheme which to me means RnRS conformance. Of course it's not exactly and every other Scheme impl is not exactly. But mostly I think that's a bug as it leads to incompatible programs. For example, there are many shell scripts out there that use == in test, because bash decided to have an extension. This is not useful, except perhaps to people writing in sh that think they are writing C :-) but it does mean that these scripts become limited to bash rather than any "POSIX sh implementation". Does the new feature advance the goal of guile as an extension language? Is this heading for inclusino in the next RnRS?
