[armedbear-devel] Extensible sequences

Hello,

has anyone ever thought of adding extensible sequences[1] to abcl? Given that our implementation of sequences is copied/adapted from CMUCL, and extensible sequences have been implemented in SBCL which is itself a fork of CMUCL, it may be as easy as copy-pasting from SBCL with minor adaptations.

Extensible sequences would allow to easily make Java collections first-class citizens in our Lisp world. This would have a number of benefits, last but not least the fact that we could easily use Clojure collections with abcl. Unfortunately I have not the time to do this myself, but if someone likes the idea and is willing to contribute...

Cheers, Alessio
