I am very interested in this. I am the current version of my own Eclasses.e
which
is based on the JAVA model of single inheritance with interfaces. Please
feel free to mine it for ideas. An area I intentionally deviated from
C++/JAVA was to separately specify read and write access for data
members--this can allow, for example, pubic read access but private write
access. This also allows a special write-access specifier: read-only. A
read-only member may be initialized but not thereafter changed.
I would love to see Joe's code when available!
