I’m curious: Is it likely that such libraries will get written by the
community? This domain does not seem to enjoy much interest. (I would
volunteer, but have neither the necessary expertise/experience nor the time.)
Can we profit from prior work? The following comes to mind:
- “User-extensible sequences in Common Lisp”, Christophe Rhodes
http://www.doc.gold.ac.uk/~mas01cr/papers/ilc2007/sequences-20070301.pdf
- Programming languages with collection APIs (among many others): Smalltalk,
Java
- Guava
