Not frequently. I'm writing a library which in a certain use case
needs a factory of Java objects passed by the user (in this case, a
Java programmer, not a Lisp programmer). I thought that I could design
my own interface to model the factory, but then I thought that I could
just pass a Lisp function, and then the idea of a more Java-friendly
general callback class (since as I said extending Function involves a
bit of boilerplate). At this point the thing is clearly more general
than my particular use case, and since Java integration is abcl's main
strength, I just thought it could be a nice addition to it.
