--enable-deprecated=LEVEL
Guile may contain features that are `deprecated'. When a feature is
- deprecated, it means that it is still there and fully functional,
- but that there is a better way of achieving the same thing, and we'd
- rather have you use this better way. This allows us to eventually
- remove the old implementation and helps to keep Guile reasonably
- clean of historic baggage.

+ which are OK but have fallen out of favour.
See the file NEWS for a list of features that are currently
deprecated. Each entry will also tell you what you should replace
The default is `--enable-deprecated=yes'.

+
+ In addition to deprecated features, Guile can also contain things
+ that are merely `discouraged'. It is OK to continue to use these
+ features in old code, but new code should avoid them since there are
+ better alternatives.
+
+ There is nothing wrong with a discouraged feature per se, but they
+ might have strange names, or be non-standard, for example. Avoiding
+ them will make your code better.
