[armedbear-devel] Extensible sequences

[Alessio Stalla]

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
