Functor and protocol based sequence library

[Eduardo Cavazos]

Hello,

A note I posted to the Ikarus list:

I'm interested in ideas from folks here as well.

Congratulations!
Very nice work, but it will be better if on a pastebin, that have
syntax highlighting. ;)

Thanks! It's just a sketch though, exploring the territory.

Here's another approach that is a bit more lightweight, using functors
but without the protocol abstraction:

Those functors are for "indexable" sequences (i.e. vectors, strings,
bytevectors).

Very nice!

Here's a similar set of functors for 'iterable' sequences:

I define some procedures for basic lists as well as the random access
lists provided by SRFI-101.

Here's the code as a set of R6RS libraries:

The '(sequences f32-vectors)' library provides an example of an
indexable sequence.
